It is about A concert band in India. Most episodes were about BSM Williams (Windsor Davies) trying to get the concert party, who he referred to as a bunch of puffs, posted up the jungle. He was always unsuccessful as the vague Colonel Reynolds (Donald Hewlett) and the stupid Captain Ashwood (Michael Knowles) were big fans of the concert party. The concert party consisted of Bombadier Solomans (George Layton), Ginger Rogers impersonator Gunner "Gloria" Beaumont (Melvyn Hayes), University educated piano player Gunner "La de da" Gunner Graham, a.k.a Padarouski (John Clegg), singer Gunner "Lofty" Sugden, Gunner Parkins (Christopher Mitchell) (Williams thought Parkins was his son, he was quite wrong), big eater Gunner "Nosher" Evans and animal impersonator's (Kenneth MacDonald), he was no Percy Edwards. Also, heavily involved in the adventures were faithful Indian servant Rangi Ram (Michael Bates), with the Char-Wallah and the Punkah-Wallah (Dino Shafeek and Babar Bhatti) giving Ram wonderful support. The show, just like Dads Army left many catchphrases. Rangi Ram used to say to his Punkah Wallah "Don't be such clever dickie" and he ended a lot of the shows saying "Here is a very old Hindu Proverb e.g When wife is having affair with best friend, it doesn't stop your house from catching fire" It was Williams though who had the most catchphrases. He would always shout "Shuddup!!!!!", say "Oh dear, how sad, never mind" and when talking to Gunner Graham, he would always sarcastically talk in a posh accent.
You don't see so much of this show now, which is a shame, it is a classic. I read somewhere that there are two reasons. One wa due to its homophobia. Williams always referring to the concert party as "Puffs". You have to bear in mind, Williams was a bore. Secondly, some politically correct obsessed morons decided it was racist and called the show "It ain't Half Racist Mum". The BBC & UK Gold seems to show Dad's Army practically every waking day and "It Ain't Half Hot Mum" should be seen more often too. It's a classic and has a big fan following.
