Sue Lawley's castaway this week is the critic and columnist A A Gill. His witty, first-person articles have earned him a whole host of awards and a loyal following. But his life as a successful writer was preceded by more than a decade that was spent living in squalid squats, taking drugs and existing in an alcoholic haze. It was the unplanned intervention of a GP that made him face up to his alcoholism and seek treatment. It's now 21 years since he last had a drink and he has been given, he says, the chance to start again and live a second life.

He abandoned his early hopes of becoming an artist, for a while he ran cookery courses in his own home and, at the same time, he started writing. Despite suffering from dyslexia so severe that he has to dictate all his columns to copytakers he found his voice immediately - as soon as he began writing his articles, he says, he felt he had come home.

Favourite track: Love Song from Sanders of the River by Paul Robeson

Sue Lawley's castaway this week is the television star Simon Cowell. Simon Cowell is one of our most successful pop music moguls. He is the mastermind behind more than 100 number one songs in Britain and abroad and Westlife, whom he signed, holds the record for having seven consecutive number one songs in the UK. A lot of his early successes were gimmicky hits - singing wrestlers, the Power Rangers and Teletubbies - but it was first Robson and Jerome and then Westlife who brought him credibility. His tenacity and his ability to spot a seller were already legendary within the music world when he devised a format for a television show that would bring new talent to the fore. Pop Idol, American Idol and now The X Factor launched the careers of Will Young and Gareth Gates among others. They've made Simon Cowell a celebrity too. His shows play to the aspirations of the young, who believe fame and fortune can be theirs. But when their ambitions exceed their talent, he's there to tell them. He's reduced many contestants to tears and been threatened by others but, he says, he's only being cruel to be kind.

Favourite track: Mack the Knife by Bobby Darin

Sue Lawley's castaway this week is the author and children's poet Michael Rosen. Since his first book, Mind Your Own Business, was published more than than 30 years ago, he has been credited with revolutionising the way children's poems are written and performed. Words and language have always formed an important part of his life. The son of two teachers, he was born into a London, Jewish family, and brought up in a home full of literature, conversation and debate. His poems often rely on snatches of dialogue and memories from his own childhood and relate his experiences with his own children.

His greatest commercial success has been his hugely popular re-telling of the American folk tale We're All Going on a Bear Hunt. More recently he's published a series of memories aimed at adults rather than children. In particular, these attend to the central tragedy of his life, the sudden death of his second son Eddie, when he was 18 years old. His death became a public matter because Eddie had featured so often in Michael's early work and was a well-known character to millions of children.

Favourite track: Black, Brown and White by Big Bill Broonzy

Sue Lawley's castaway this week is a playwright whose work has chronicled Britain's changing political landscape over the past 30 years. David Edgar was brought up in a leafy suburb of Birmingham, but was radicalised during the 1960s and has never looked back. In 1976, he examined the right-wing National Front movement in Destiny, a play for the RSC. It was his first award-winning play and the work of which to date he is the most proud.

His interest in theatre goes back to his childhood; his parents both had theatrical connections and his father even turned a garden shed into an elaborate theatre. It was here that as a boy he was to star in plays in which he cast himself in the leading role. Despite the shift of politics to the centre ground, he remains committed to the left-wing cause and to exploring the difference between utopia and reality. He also writes for TV and radio, and his plays are regularly performed on the international as well as the British stage.

Favourite track: Cum Sancto Spiritu - With the Holy Ghost by Johann Sebastian Bach

Sue Lawley's castaway this week is the psychoanalyst Dr Hanna Segal. Hanna Segal is one of the most distinguished psychoanalysts of our time. She was born in Poland at the end of the First World War and after a sometimes difficult childhood her family moved to Switzerland and then France to flee the Nazis. They ended up on a Polish troop ship that brought them to Britain just in time, as she says, for the Blitz.

As a teenager she was passionate about aesthetics and politics but did not know how how to combine her passions in a career - once she discovered the work of Sigmund Freud she knew her calling lay in psychoanalysis. Her mentor was Melanie Klein and she wrote what has become a standard text about her work. Dr Segal has written too about psychoanalysis and aesthetics and our response to the threat posed by nuclear weapons. She has held the post of Freud Professor at University College London and is a past president of the British Psychoanalytical Society. Now aged 87, she continues to work overseeing student analysts and giving seminars.

Sue Lawley's castaway this week is the writer Ian Rankin. Ian Rankin is an award-winning writer of crime fiction and the creator of the Scottish detective John Rebus who has featured in 17 novels to date.

Born in Fife, Rankin came from a working-class background in a coal-mining town where he says he spent most of his childhood trying to "look like he fitted in". In his bedroom he would live out a fantasy life, writing poems, stories and creating strip-cartoons. He admits there are many parallels between himself and Rebus - they lived at the same Edinburgh address, both are fond of a drink and now they even share the same taste in music, though unlike Rebus, Rankin has never smoked. However all that is about to change; Rebus has reached the age of retirement in the police force and Rankin's next novel will be the last in the series.

Sue Lawley's castaway this week is the gardener and broadcaster, Monty Don. Three years ago Monty Don became the nation's most high-profile gardener when he took over from Alan Titchmarsh as the lead presenter of Gardener's World. Entirely self-taught, he has been gardening since he was a child - but it was not until he was in his late thirties that he found he could make his great passion become his vocation.

His first career ended disastrously; he and his wife Sarah set up a jewellery business together and during the 1980s they prospered; they had shops and offices in Knightsbridge and counted singers and film stars among their clients. But when the slump came they lost everything - the business, their jobs and their home.

Monty suffered years of depression that left him barely able to function. It was by chance that he was offered some stints presenting gardening slots on television. He never looked back - he says there hasn't been a day since when he's not been working and he's become a successful gardening columnist, broadcaster and author.

Favourite track: A Hard Day's Night by The Beatles

Sue Lawley's castaway this week is the chief executive of BP, John Browne. His father had also worked for the company and through visits to Iran as a boy, he witnessed spectacular oil-well blow-outs which gave him a fascination for the business. He joined BP after leaving university, starting at the sharp end as a petroleum engineer in Alaska in the 1970s. For 20 years, he travelled the world, working his way up the ladder before permanently settling in London.

Almost 10 years ago, he said that oil companies must take seriously the threat of global warming and take measures to tackle the issue. He was knighted in 1998, and created a life peer in 2001 as Lord Browne of Madingley.

Sue Lawley's castaway this week is the Nobel prize-winning physicist Sir Peter Mansfield. His work in magnetic resonance imaging more than 30 years ago led to the development of the MRI scanner, which has revolutionised the diagnosis of illness today.

He was born in London before the Second World War and as a boy, remembers the first Doodlebug attack on the capital. Watching the flying bombs gave him an interest in rocket propulsion which was to lead to a life-long career in science. The son of a gas-fitter, he left school without O levels at the age of 15. His school careers' officer had laughed at his ambition to be a scientist and fixed him up with a job as a printer. He put himself through night school, and went on to graduate with a first class degree in physics.

The first MRI scan was performed using him as the guinea-pig and with next-of-kin on hand because of the risks involved. His pioneering research was carried out at the University of Nottingham where he became Emeritus Professor of Physics. In 2003 he was jointly awarded the Nobel Prize for Medicine at the age of 70.

Sue Lawley's castaway this week is the retail legend George Davies. In the 1980s he changed the shape of our high streets with his chain Next. In the 1990s he made supermarket clothes fashionable with his George range for Asda and in 2001 he launched his Per Una collection in Marks and Spencer - it's credited with helping the store find renewed financial success. He was brought up in Liverpool and showed early promise as a footballer - he was talent-spotted by the legendary Bill Shankly, but wasn't good enough to play at the highest level. Then he nearly became a dentist but, after dropping out of university, found a job with Littlewoods as stock controller in charge of children's ankle socks. From the day he started he says he never looked back - he knew his future lay in retail.

His trick is knowing his market, and he does that by carefully studying the details of how his clothes sell. Each week he analyses sales figures for every garment, in every store up and down the country - the result, he says, is that he not only knows what women like, he knows what they think.
