I'm not the one on dangerous ground, Jon.

At any rate, I am not bringing this up on strictly legal grounds, I doubt anyone would go to the trouble of suing, but if you are not careful, you can create bad feelings and animosities that last for a very long time-- The world of folk music and dance is a small one, the dance people particularly are often very territorial about their work(not being judgmental here, just pointing out a fact), and I have seen dance leaders, in innocent enthusiasm, recreate someone's workshop when they get back home, duplicate it a few times, and then have the original workshop teacher say, "Who the hell do they think they are. stealing my dances, my breakdowns, even my jokes, and passing themselves as experts?"

Like I said, a cassette is one thing, because the recording quality isn't that good to begin with, and the copies will even worse, but with a CD, you can clean it up, re-arrange, organize, and circulate it to others, eager to use it to teach, learn, give workshops of their own, heck, even start a performing group--

As I said, bad feelings can last for years, so be a bit circumspect--
