Can I be controversial (again) and ask when is a song a "Folk" song?
Does it have to be:
a) Over 100 years old?
b) Of forgotten origin?
c) Reflecting the the daily lives of ordinary folk?
Personally, I vote for c).
Just because we know the authors name and (perish the thought) they may even be still alive, does not prevent their music from being "Folk".
I'm thinking of great artists such as Ewan MacColl, Harvey Andrews, Kieran Halpin......the list goes on.
What say the rest of you?
