They find the three groups in different locations and enlist their talents for the show.

Bruce Beresford directs this 1970s musical comedy starring Barry Humphries and Terry Thomas. In the small town of Sludgley, two nightclubs try to outdo each other by booking the best British bands they can get hold of when the local authorities uncover an age-old law that means only one of them can remain open. The film includes performances by Mud, The Rubettes, Kenny and many others.
