I don't think 'folk' has anything to do with the words we sing or the music we play. For me it's far more about the way we communicate with each other - which is generally on a highly personal basis that doeS not rely on special effects or mic enhancements. But comes from the heart in such a simple form that is very easy for others to emulate or aspire to.

Of course, folk has its super stars but promoters need them to fill venues but there is just as much quality music found (certainly here in the UK) in the local folk club or festival.

Folk is about respect for the song, the songwriter and the music and the musician.

It's about being part of an extended family in a much more personal way than being a member of a fan club.

I have a friend who is a Beatles fan, she goes to all the conventions yet worships from afar. After 40 years her dearest wish is still to meet one of them.
My heroes are real - I've met them - talked to them and am fortunate to count some as my friends.

THATS WHAT PUTS THE 'FOLK' INTO FOLK MUSIC.
