Australia has always prided itself on its sense of humour. Peter Luck talks with old vaudevillians like Ron Shand and Jenny Howard, comedian Roy "Mo" Rene's widow Sadie Van de Sluice; and others including Barry Humphries (better known as Dame Edna Everage) and Garry (Norman Gunston) McDonald. The programme covers early Australian humour, the work of "Mo" and George Wallace and the TV comics of today.
