Haven't been through the huge number of replies, so my own might well be repetition, for which my apologies.

Rambling Syd Rumpo was a charatcer played by KW in a BBC radio programme of the 1960s called "Round The Horne," starring straight man Kenneth Horne. Rambling Syd himself was a West Country yokel, full of country knowledge (so he thought) and colourful Williamesque country expressions. He was also a "folk singer" whose repertoire consisted of almost unintelligeable yet very double-entendre country lyrics sung very tongue-in-cheek, of course, by Kenneth.

"Round the Horne" was also the home of Julian and Sandy, in which KW played alongside Hugh Paddick. They were a clearly gay couple (very risqué at the time!) with a new angle in work each week. Again, full of double-entendre, much of which was probably lost on a great deal of the listeners at the time, as this was something completely different, of course.
