It Ain't Half Hot Mum - Season 5 (1977)

A load of Christmas puddings are dropped by air into the camp, each with the name of a high-ranking officer on them. Captain Bishop arrives and requests that the puddings be given to him but a second officer reveals that Bishop is an impostor, who wants to sell the puddings on the black market. The puddings are returned but it would be bad publicity if it was known that some officers were being awarded preferential treatment and given their own Christmas puddings, so they are given to the audience to eat and destroy the evidence, whilst Rangi keeps several for himself.

Unassuming aircraftsman Ormanroyd joins the concert party. He is a superb singer, a talented multi-instrumentalist and a more than competent ventriloquist. It is decided that he will replace Lofty, who will be returned to ordinary duties. At the same time word arrives that a female impersonator is required for a show in Calcutta. It could be Gloria's big opportunity. However Gloria's loyalty to Lofty outweighs his ambition so he lets Ormanroyd take the Calcutta job, allowing his little mate to stay in the party.
