After the success of "Peep Show", Mitchell and Webb returned to sketch comedy with their BBC Radio 4 sketch show "That Mitchell and Webb Sound", which ran for five series. The show was adapted for television and became "That Mitchell and Webb Look", producer Gareth Edwards described it as "the shortest pitch (he had) ever written". Towards the end of 2006 the pair made their first tour, with a show called "The Two Faces of Mitchell and Webb". The tour was criticised as just "a succession of largely unrelated scenes" by "The Guardian"s Brian Logan, who gave it a rating of two stars.
