There's a hole in my bucket!!

This was always a lot of fun. We would ask for a volunteer from the audience and then ask her to sing the female part of the song "there's a hole in my bucket"
Jimmy would sing the male part and I would tell the "volunteer" the wrong words to sing. It was different every time we did it and always quite hilarious. Everyone who ever helped out was great. Unfortunately I don't remember who this was on this occasion, but I think she had already caught on to what was happening.
Actually the funniest one of all was at the Red Lion in Brentford, near London. There our volunteer was a French girl who didn't speak English.
