Career: While still presenting, Brydon ventured into comedy, and made ends meet by providing voices for adverts and animations. A small role in Lock, Stock and Two Smoking Barrels inspired him to make a short film of his comic characters; series of Marion & Geoff, A Small Summer Party and The Keith Barret Show followed. Other credits include Director's Commentary, Human Remains, Supernova, A Cock and Bull Story, Little Britain, Annually Retentive and Gavin & Stacey. He's also hosted his own BBC chat show and has chaired the comedy panel show Would I Lie to You? since 2009. In 2010, he starred alongside Steve Coogan in the partially improvised BBC Two sitcom The Trip and has since appeared in its follow-up.

Career: After graduating, Mitchell worked an usher at the Lyric Theatre, Hammersmith. He and Webb took a number of shows to the Edinburgh Fringe Festival before being asked to write for Alexander Armstrong and Ben Miller and for surreal comedy series Big Train. In 2001, they made their first sketch show, The Mitchell and Webb Situation, which ran for six episodes on the now-defunct cable channel Play UK. Their next project came in 2003, with the award-winning Channel 4 sitcom Peep Show. They've also worked together on That Mitchell and Webb Sound, That Mitchell and Webb Look and the film Magicians. Solo, Mitchell has appeared on 10 O'Clock Live and numerous panel shows, including Would I Lie to You?, where he's a regular team captain. His autobiography, Back Story: A Memoir, was published in 2012.

Career: His success as a stand-up was crowned when he won an award at the Edinburgh Fringe Festival. He came to the attention of TV bosses after a stint on the radio. Lee was cast in The Sketch show alongside long-term collaborator Tim Vine. After a short-lived stint presenting They Think It's All Over, Mack and Vine began work on Not Going Out. The series revolves around two friends with opposite backgrounds and personalities, much like the two comics themselves. Mack has recently become a regular on comedy panel shows such as Would I Lie to You? and Have I Got News for You. He also has sell-out tours and best-selling DVDs to his name.

Career: Like bread and butter, Giedroyc and Sue Perkins go well together - in fact, they're almost inseparable in professional terms. They were a hit at the Edinburgh Festival in 1993, and went on to write scripts for French and Saunders before presenting comedy chat show Light/Late Lunch and RI:SE. She was also in the children's sketch show Sorry I've Got No Head. More recently she has scored another hit with The Great British Bake-Off, alongside Sue, and daytime ITV show, Mel and Sue. Her radio work has included The 4 O'Clock Show on Radio 4 Extra.

Career: Mortimer became involved with the act, which gained a cult following among celebrities. This led to Channel 4 series Vic Reeves's Big Night Out. Its success prompted him to give up his law career. A move to the BBC in 1993 saw Mortimer get equal billing for the first time. Since then, their shows The Smell of Reeves and Mortimer, Shooting Stars, Bang, Bang It's Reeves and Mortimer, and Randall and Hopkirk (Deceased) have been hits. They also penned and appeared in The All Star Comedy Show (with colleague Steve Coogan), and Vic and Bob in Catterick. For years he's claimed that he and Reeves are working on a sitcom about superheroes, but it's yet to see the light of day. Instead, their most recent project has been House of Fools for BBC Two.

Career: In 2002, Ray joined the BBC Asian Network to present the late night Adil Ray Show. He presented other slots on the station before leaving in June 2010. He has since been a regular on BBC Radio 5 Live. Since 2012, he has co-written and starred in the BBC sitcom Citizen Khan. He has also presented Desi DNA and Inside Out. In 2015, he guest presented three episodes of The One Show.

Career: In 1998, Westlife started out as a support act for Boyzone and the Backstreet Boys. A year later, their first single, Swear It Again, topped the charts in Ireland and the UK. Westlife went on to sell more than 50 million records worldwide and achieved 14 number-one singles in the UK. They announced their intention to split in 2012 and played their final concerts in June of the same year at Croke Park Stadium in Dublin. Away from Westlife, Egan has been one of the coaches on talent show The Voice of Ireland, and co-presented a series of Surprise Surprise. In November 2013, he was a contestant on I'm a Celebrity Get Me Out of Here!
