Bit of a funny thread, but I remember a camping holiday in Scotland in 1974 when we had to walk four miles there and four (pissed) miles back to get to the nearest pub to the campsite (in Killin, Perthshire). We sang this song, exactly as in the opening post, to keep us going on the long slog back. To do it right, you have to do some almost orgasmic singing on the "Oh, Sir Jasper!" line!

And "She's a most immoral lady" is a key part of the song!
