Before many of the shows became generally available on cassette, I worked for the BBC and often spent an interesting lunch hour prowling the the stacks of the Sound Archives department - a fascinating place. I recall coming across a shelf of Goon recordings, all on vinyl. I was allowed to take them home, one at a time each evening, to play at home and then return in the morning. Hours of fun.

I think my favourite is still "The Scarlet Capsule" - a piss-take of the "Quatermass And The Pit" story.
