for fucks sake, john p, iknow nothing about you,but i will tell you a little about myself and also banjiman.
i have been playing traditional music and american folk music for over 40 years , i have a websitehttp://www.dickmiles.com, i have been involved with running folk clubs too ., i have written 2 concertina tutors, and a song book
Banjiman plays the banjo runs a club and plays with his wife who is an excellent singer.
I cant speak for banjiman,
BUT I DONT LIKE TRAD MUSIC PLAYED BY A ROCK BAND , BUT I AM NOT A PURIST. you see i dont attempt to stop rockbands from playing trad music, neither do i say to unaccompanied singers you must accompany yourself.
in my opinion a purist is someone who runs a singers club and refuses to let singers accompany themselves, the sort of people who you have given your support to, the sort of people who enjoy telling others you cant do that there here.
so we even have different opinions as to what constitutes a purist
