If I were a fan of medieval church music, I would want to take every opportunity to hear medieval church music, meet other enthusiasts, find out about examples of medieval church music that I didn't know, learn to play medieval church music, perhaps even put on my own performances.

Folk's no different. If you're into traditional music, you're really into it, and you want to go to places where you can hear (and sing) more of it.

But what I wouldn't do, if I were a fan of medieval church music, is write new pieces, announce that they were medieval church music and insist on playing them to the exclusion of the originals - even at a medieval church music club.

Apparently folk is different. Why?
