I have head that one before, but not 'attached' to you mate... so yer in the clear I'd imagine...

"Now I've been a folk-singer for many a year
*hic* Can ya... *hic* sshhhling The Wild Rover?", is all that I hear
So I think I'll retire and live on the dole
Where I won't have to sing The Wild Rover NO MORE!"

Is the verse I use at the end... it almost always get a really good laugh from the crowd...
