DJ and radio presenter Trevor Nelson grew up in London and came to find out he had half siblings on the Caribbean island of St Lucia. However, for Trevor and his three sisters who were raised by his parents in the UK, this was something that didn't really have an impact on his family life until much later when Trevor finally met his half siblings.

It's something that has fascinated Trevor all his life, and now in this series of One to One, he meets people to uncover what it's like to have, or to find out you have, half siblings.

In this programme, Trevor meets Adrienne who has eight half siblings but no full brothers and sisters. She tells Trevor that that there is no jealousy and rivalry and that they really are one big happy family. Really?

Mark Steel is obsessed with sport. Obsessed! And he's certain there's a strong link between sport and stand-up comedy - risk taking, dealing with a hostile crowd, performance anxiety. In this programme he muses on his theory with the snooker player known as 'The Entertainer', John Parrott.

For this series of three programmes, he also meets sports psychologist and former figure skater, Dr. Faye Didymus; and also the former Premiership and England footballer Graeme Le Saux.

You can hear extra bits from both interviews on the podcasts, just go to the Radio 4 website.

Produced in Bristol by Karen Gregor.

Mark Steel's guest this week is impressed by his flow-state, but would like him to reduce his dependence on ironing. She is sports psychologist, Dr. Faye Didymus, from Leeds Beckett University.

Mark believes that his two addictions have much in common - they are stand-up comedy (his job) and sport (watching, playing, talking about it). He's sure that there is a link between the way comedians and sporting types deal with performance anxiety, crowd hostility, risk taking and more. Dr. Didymus, who works with sports stars at the highest level, casts light upon this theory.

In this series, Mark speaks to the former Premiership and England footballer, Graeme Le Saux. And he meets former World Champion snooker player, John Parrott. All three programmes are available as podcasts, and the Parrott & Le Saux podcasts have extra bits.

Mark Steel has two addictions: stand-up comedy (his job) and sport (watching, playing, talking about it). He's certain that the two have much in common - risk taking, performance anxiety, dealing with crowd hostility and more. His guest this week is former Premiership and England footballer, Graeme Le Saux, whose strategies for coping with playing at the highest level are more similar than you might think to Mark's own experiences - especially when it comes to dealing with crowds who don't really like you.

In this series, he meets Dr. Faye Didymus, a sports psychologist at Leeds Beckett University (who was impressed by his flow-state, but would like him to reduce his dependence on ironing). And Mark also meets former World Champion snooker player, John Parrott. All three programmes are available as podcasts after broadcast. And there are extra, un-broadcast, bits in the John Parrott & Graeme Le Saux podcasts.

Miranda Rae meets Gill Sargent to explore the challenges of being a single mum with a child of dual heritage - something they both have in common. Life for any single parent is far from easy, but whilst trying to raise her son, Gill has also had to endure prejudice and racism in addition to exhaustion, isolation and homelessness. Producer Sarah Blunt.

Miranda Rae is a single mum with a young son who is 9 years old. Life is far from easy for any single parent, but in this programme Miranda meets mother-of-three, Josephine Pepper, who found herself on her own with 3 children under the age of three, when her husband died of cancer. Despite her grief at the death of her husband, Josephine's story is one of remarkable courage, resilience and joy in her children and in life itself. Producer Sarah Blunt.

Lucy Mangan avoids responsibility wherever possible. She's got cats instead of dogs because she can't face a needy pet; she only has one child 'and that's more than enough.' But she's always been fascinated by those who run towards responsibility rather than away from it. Today she talks to Reverend Claire Herbert about a life dedicated to helping others. One of the first women priests to be ordained, Claire was working as a rector at St Anne's church in Soho when the Admiral Duncan bomb exploded. But she admits that being there for others has not been an easy road - in her 30s she took some time out from full-time church work to become a social worker and learn to be young 'perhaps for the first time'; she has realized that she needs to learn to play, and now gives herself permission sometimes to be 'naughty and horrible.'.

Lucy Mangan feels she avoids responsibility whenever possible. She has cats instead of dogs because she can't face a needy pet; she only has one child which is 'more than enough'. But she's always been fascinated by those who run towards responsibility rather than away from it. She talks to Bea Harvie, a post-graduate student, whose father got ill when she was thirteen. Bea chose to take on a lot of caring duties towards her younger siblings while her Mother was busy caring for her Father. She describes the experience as something she just got on with, and reveals that it also was a useful distraction from dealing with her own feelings about her Dad's illness. Until one day when she was sixteen and it all caught up with her. She says its like shaking up a bottle of fizzy pop: ' it's got to come out some way.'.
