Tier Blundell was never a bad kid, he was bright and curious but also disruptive. He grew up sandwiched between two cultures and felt excluded from society. Those feelings were amplified when aged 11 Tier was informed by his school that he wouldn’t be welcome back following the summer holidays and was instead sent to a Pupil Referral Unit. He left there with no qualifications and a sense of shame, until the day he puts on a suit, turns up for an unscheduled meeting and demands another go at education — and the results are staggering.

Su Chantry was adopted as a baby and grew up fantasising that she was the daughter of a French princess who would one day return for her. As an adult with her own family, Su received an unexpected phone call. She rushed to meet her mum, and they would spend just one day together, her last.

Aged 19, Dan Simmonds turned down a university place and instead became an oil trader in the City of London. It was an exciting and ruthless environment driven by big risks and even greater rewards but also ultimately challenged Dan’s values and filled him with a desire to seek something new. Over a decade later whilst jogging around Regent’s Park Dan made a discovery that would change his life and career.

Agnes Nisbett is a nurse and midwife whose own hospital experience in the 1970s revealed just how flawed and uncaring the system could be. Agnes came to the UK from St Kitts and Nevis as part of the Windrush generation. Her goal was to achieve as much as she could in her profession and despite the many barriers, “sheer hard work” got her to the top. Now in her eighties and looking back on her time in the NHS, she shares how her own private and personal loss inspired her to challenge and change things for others.

Georgia Gabriel-Hooper is now 20, she works for a tractor dealership and enjoys bumbling around the countryside.

In this special edition of Life Changing, recorded in front of a live audience at the Hay Festival, we are catching up with Harriet Ware-Austin, who was a guest on the programme in 2021.

Harriet had a difficult but important story to tell, concerning the deaths of her two sisters in a plane crash in Addis Ababa in April 1972. Harriet was only eight at the time and witnessed the event. Almost 50 years on, Harriet joined us to talk about the profound and long-lasting effects it had on her family. She also wanted to see if there was anyone else out there who had a connection to East African Airways Flight 720, but was totally unprepared for the extraordinary response her interview received.

Two years later, this is the story of what happened after that interview and how it has been life-changing all over again.

This episode was recorded in front of a live audience at the Hay Festival in May 2023.

When Alan and Irene met in 1959, their connection was instant. The two isolated children aged just seven and nine found warmth and kindness in each other in a children’s home that was unwelcoming and strict. They would steal moments together up on Bunny Hill and talk about their lives. But the home had a rule that boys and girls could not mix. So when their friendship was discovered, a year after they first met, Alan and Irene were separated. It would take four decades for them to find each other again.

In August of 2006, Teresa Clark was driving five of her friends back home after a day at a music festival. Several hours into the journey she fell asleep at the wheel of their people carrier and crashed. Three passengers were killed, two others were injured as well as Teresa herself.

She was convicted of causing death by dangerous driving and spent time in prison. The guilt and shame of carrying that loss of life almost destroyed her. But in the 17 years since it happened Teresa has rebuilt; she now works in the mental health and wellbeing sector trying to keep the vow she made to live her life for her friends, and do some good in their memory.
