It was 'I'm Sorry, I'll Read That Again' which had fun in the '60's beeping out the lyrics of popular songs. I can remember 'It's Not Unusual' (to have 'beep' with anyone), and 'Jake The Peg (with the extra 'beep').

Like so much in that programme, (and indeed like me), it was puerile, potentially offensive and has not stood the test of time, but you had to be there. I can remember an entire pub bar emptying for half an hour so that people could sit in their cars and listen to it. I don't think the landlord ever quite realised what was going on.
