By the way Bruce Olsen (if you are still around?) - a folk song is one that folk sing!
A folk song is about HOW you sing it -- - and you should feel free to adapt it to your own style and understanding.
My pal Iain writes songs, and there are people who thing some of his are old undiscovered f9olk songs----!
Not that he deliberately sets out to do this, just something about his style - --
I guess it is difficult if you are a member of the Folk Police- - - -
