While we're on the topic..A friend of mine apparently heard a parody of this while he was in Ireland that was great, but that isn't in the database... unfortunately, due to my being a space cadet, I don't remember the lyrics he was able to sing for me, and so can't ask now, but I'm hoping that if I post here, I'll be able to find this again later!
I'll get back to you...
Cheers, Jessica
