The comedian chats to the British rapper about how his life has been affected by his father's suicide, the breakdown of his marriage and a near fatal stabbing.

The comedian chats to the writer and actress about creating and starring in Gavin & Stacey, and her more recent foray into writing novels.

The Take Me Out presenter discusses his life and career, reflecting on his relationship with regular co-star Peter Kaye and his experiences as a father to two autistic children.

John chats to Canadian stand-up comic Katherine Ryan, known for her prickly and provocative humour. Now based in London, Katherine has managed to balance being a single mother with building a successful stand-up career, as well as becoming a firm fixture on panel shows like Mock the Week, QI and 8 Out of 10 Cats and recently releasing her first Netflix special, Katherine Ryan: In Trouble.

John pulls up a chair with New Zealand ballroom dancer Brendan Cole. Specialising in Latin American dancing, Brendan shot to fame on Strictly Come Dancing and, over fifteen series, was partnered with the likes of Sophie Ellis-Bextor, Lulu, Natasha Kaplinsky and Kelly Brook. Brendan was also a judge for four years on New Zealand's Dancing with the Stars and was runner-up on Love Island in 2006.

John chats to singer-songwriter Will Young who, as the winner of the inaugural series of ITV's Pop Idol in 2002, was one of the very first stars to emerge from the resurgence of TV talent contests. Proving that longevity is actually possible for a reality pop star, Will has released best-selling albums that have also been well received by the music critics, but things haven't always been smooth sailing along the way.

American actor Cuba Gooding Jr opens up to John about his roller coaster career. Aged 22, Cuba scored his first major role as the lead character in John Singleton's groundbreaking inner-city drama Boyz n the Hood. Five years later he'd won an Oscar for Best Supporting Actor in Cameron Crowe's blockbuster sports movie Jerry Maguire. More recently, he's portrayed O.J. Simpson in an acclaimed TV drama.

John talks to Alesha Dixon, the multi-talented singer, rapper, model and TV personality. After finding fame with British girl group Mis-Teeq, Alesha's solo career stalled when her first singles fared poorly. Winning Strictly Come Dancing in 2007 turned everything around and she went on to release acclaimed albums alongside TV presenting work including becoming a judge on Strictly and then Britain's Got Talent.

John sits down with Gabby Logan, four times winner of 'Sports Presenter of the Year'. Gabby began her career at a time when very few female sports presenters had made the transition to terrestrial TV but, with a father who was a Welsh international footballer and later manager, Gabby was immersed in sport from an early age and herself went on to represent Wales at the 1990 Commonwealth Games in gymnastics.

In the final episode, John catches up with actress and singer Martine McCutcheon. Playing Tiffany Mitchell in EastEnders and appearing in the John Curtis romantic comedy Love Actually made her a household name, but Martine chose a more musical direction with a pop career and her role as Eliza Doolittle in the stage musical My Fair Lady which bagged her a Laurence Olivier Award in 2002.
