Season 1: Episode 8

The Sergeant Major wants the men from the Concert Party to do guard duty and drill. The Colonel points out that they all have different uniforms, so they wouldn't look right on guard. The Sergeant Major plans to get the gang to dress up in similar uniforms by persuading them to include a 'military' number in the show. Solly manages to get hold of some uniforms and begins to rehearse 'The Road To Mandalay'. The General pays a visit to inspect the camp. He complains about the fact that the men in the camp all seem to be wearing different uniforms. Then he sees the Sergeant Major drilling the Concert Party, all dressed in similar uniforms, and insists on inspecting them.
