American Musical (sometimes simply called Musical) was a game played during the early years of the British programme.
Before the start of the game, Clive Anderson brieflys interview one to three members of the audience. This way, he gets three suggestions for topics. The performers, in whatever order they wish to join, act out an American musical about those three topics.
One of the final playings, with the topics of taking a course about business, coming third in a rock and roll championship, and visiting Australia, was among the most memorable. It featured Greg Proops, Mike McShane, Ryan Stiles, and Josie Lawrence singing about their rock band, "The Bitchin' Wallabies".
