Excuse me Diane
If everyone thought like you there would be far fewer people interested in Folk as if they are not excellent at it they would assume they shouldn't participate.
I will be bringing my son up to enjoy all aspects of Folk and if he is interested in learning and joining in with any aspect I will positively encourage him regardless of his ability.
I have performed at several festivals as a booked artist, I am not spectacular but I have never heard anyone complain that as I am not perfect I shouldn't be performing. I do not dumb down and I try to find out origins to the songs which I perform. (something which has to be done now by law)
It is people like me who are bringing up today's and tomorrow's generations to enjoy and appreciate folk and who will contribute to keeping folk alive - at all levels.
Diane, Ralphie, and others: Please keep your personal squabbles, personal. We don't care to be drawn into them.
