Hugh Dennis hosts this series in which six radio presenters, one from each of the six BBC radio stations, Radio 1 through to 6Music, are given just two weeks to become fully-fledged stand-up comedians by performing their first proper gig in front of the general public at London's famous comedy venue, The Comedy Store.

The contestants are: Dev from Radio 1, Tony Blackburn from Radio 2, Tom Service from Radio 3, Jenni Murray from Radio 4, Tony Livesey from 5 live and Shaun Keaveny from 6 Music.

To help them on their way though, each of them is paired up with a mentor who will try to help them steer clear of the many pitfalls of performing stand-up comedy. Dev is mentored by Chris Ramsey, Tony Blackburn by Julian Clary, Tom Service by Sandi Toksvig, Jenni Murray by Mark Steel, Tony Livesey by Justin Moorhouse and Shaun Keaveny by Miles Jupp. Between them they hope to win the title of Stand Up for Comic Relief champion!

This programme sees the presenters doing their first try-out night and we hear how the mentors think their charges are coming along ahead of the big gig itself.
