At one folk club we would always finish with "Wild Mountain Thyme" which would be sung round the room, a verse from each singer. If there were a lot of singers it would difficult to find a verse so I used to write a new one every week - people even used to pinch what I'd sung the previous week and get in first with it.

One of my worst was:

If my truelove chucks me out
Then her love she can keep
I'll just pull on my wellies
And I'll find myself a sheep


I still often hear it sung by complete strangers.
