I think anything is fair game for the folk genre. If a song/tune/snippet is perpetuated by the living it meets my definition of folk, and unless someone can shew me a definitive definition ... well, mine is it ;o)

You can buy the sheet music and play exactly what the Beatles wrote or you can 'fiddle' with it. And if superannuation is a must in your definition I guess time will win that argument.

Someone said it's all to do with how it sounds. Naa, can't agree there. I think everyone would agree Waly Waly and The Black Velvet Band are folk songs but they're not very similar in sound.

My penno'th.
