I have Mike Harding singing it on A Lancashire Lad album too.

When I started reading the thread, my mind drifted to a poem about a girl's knee, which I think was written by Bill Oddie;

There's a girl in 3C with a wart on her knee
And a pimple upon her behind.
I gave her 3p and she showed it to me
Don't you think that was awfully kind?

ps Wonder what she'd do for a wine gum?
