The Goons

The Goon Show was an audio comic strip featuring Spike Milligan (who basically wrote the series), Harry Seacombe (heroic Welsh tenor) and Peter Sellers (no mean shakes as a voice-man, himself).  Programs and scripts are available at the Internet Archive.

This bit is a pretty good mental picture of how the program sounded, and shows how some things can only be turned into what they already are.
