Confessions Of A Pop Performer (1975)

"Our name is Kipper, Kipper/Mean as Jack The Ripper"

Robin Askwith abandons his window-cleaning round to help organize a tour for Kipper - a band of no-hopers - and finds himself knee-deep in groupies.

Askwith struggles manfully with a dismal script and comes off much better than Prime Minister Blair's father-in-law, Anthony Booth. 

Particularly in the scene where Booth is frantically shagging the arse off Jill Gascoigne (that's Jill Gascoigne) with ridiculous Benny Hill facial contortions, in an attempt to get his brother's crappy band on Opportunity Knocks "satirical spoof" show Star Knockers.

The finale at the Palladium (performed in front of Her Majesty and the Duke of Ed - represented, as they always were in comedy films of the time, by a single gloved hand and a corgi - "I think the ol' Joanna comes in 'ere!" - has to be seen to be believed).

Among the other familiar faces are Doris Hare from On the Buses and Benny Hill's long-time accomplice, Bob Todd. 

Jill Gascoigne allegedly tried to stop the release of Confessions of a Pop Performer on video, claiming the distributors were trying to cash in on her success in The Gentle Touch.

Watch for Ian Lavender (Private Pike from Dad's Army) as a Police Constable on heat with a WPC in a storeroom.
