Here's one I wasn't asked to play.  I wasn't asked not to play it either so as it doesn't seem to be here already I thought I'd give it a go.  I think I was half the age I am now when I last played this tune and if I live to be twice the age I am now I'll either have too few teeth or too much sense to play it again.

There's a touch of a farting in the bath sound about it.  Maybe it's more of a windpipe than a hornpipe.
