The Keith Barret Show is a spoof BBC chat show hosted by Keith Barret who interviews celebrity couples in the hope of finding the secret to a successful marriage. It was devised by Paul Duddridge and co written with Rob Brydon. In each programme, there are a selection of clips from venues such as speed dating or interviews with relationship experts. Rob Brydon's character Keith first appeared on TV in the cult comedy series Marion and Geoff where, for most of the first series, he was oblivious to the affair between the title characters. This was not the first BBC interview programme to be hosted by a fictional character - Brydon's close collaborator, Steve Coogan used the character of Alan Partridge with much more disastrous on-screen effects several years earlier.
