"Shimrod. That's a dangerous argument. Why? Because it will have people believing that change and 'community ownership' are enough to negate the need for credit/attribution/copyright etc. This is because most believe that Trad = Publicly Owned.

So they'll decide that Changed/owned by community (=Trad) = Out of Copyright. Which is NOT the case - you see?"

Dear 'Someone else',

Are you actually saying what I think you're saying?
I think you're saying (and I hope I'm wrong) that a coherent and logical description of Folk/Traditional music should actually be suppressed for commercial/political reasons? Now that's what I call dangerous!!
