Folk Songs

My 12 year old son was telling me about some songs he had learned for chorus this year. Yellow Submarine, Thriller, and "that really famous British folk song". What really famous folk song? I ask. "You know mom, that one about having to go to the bathroom". No, I really don't know. So he sings a little for me. I think you may be familiar with this tune. "Skip, skip, skip to the loo, My Darling."
