Improvised character comedy show for Radio 4 in the shape of a traditional chat show.

Like many chat shows, there's one host, guests and a studio audience. However in this case the guests are all comedy performers who don't know who they will be playing until literally seconds before they appear. That's because their identities, backgrounds and life stories - and the questions that host Justin Edwards will ask - are chosen randomly from suggestions from the audience.

When the guests appear, the host engages with them like any good chat show host and the performers must go with it. But even then extra curveballs are thrown along the way as more facets of the guests' pasts are drawn from the audience suggestions. At the end of each interview, the 'guest' is asked to give some kind of performance whether singing or a demonstration of a special skill.

James Sherwood provides musical accompaniment.

Guests include Sandi Toksvig, Jeremy Hardy, Matt Lucas, Rebecca Front, Hugh Dennis, Simon Day, Charlie Higson and Mel Giedroyc.
