In looking for the backups for my Brain, I've refound a sketch that was banned by the Lord Chamberlain. He (or, in practice, his staff) was in charge of stage censorship in the UK until it was abolished in the late 1960s.
It was intended to be in a show called 'Guarding the Change' at – I think – the Lyric Theatre Hammersmith, and turned out to have been written by Clive James (there's a comment about it in May Day was in June)

Hmm, hardly desparately dangerous stuff, but obviously too disrespectful of royalty for 1965!
