Thanks - thats a lot more words for the straight version than I'd previously found. What's this Homer and Jethro version?

The bloke I heard it from is a pianist who used to play it in a concert party in Plymouth (England) in the 50s and early 60s. Someone else suggested that Bennie Hill had used the verse about the cow, but I would have thought that would have to have been later, so maybe he pinched it.
