My favourite was "The intros and the outros". I think it was on the strength of that that Mike Oldfield got Viv Stanshall to do the voiceover on "Tubular bells".
Some time ago some friends were staying, and their teenage son played the theremin. He gave us a demo - weird sound!
I played a few cricket matches with Sam Spoons (real name Martin Ash) from the Bonzos. He was an old boy of the school I went to, though we were playing for a club.
