Well, I'm not the administrator either, but I am happy to see someone speaking out in support of copyright for living composers. Sharing of PD sites is probably no sin, but stating that you can find a work clearly still in copyright there free might be. Morally anyway.
I'm sure Jay Ungar has lost control of Ashokan Farewell completely (and probably Wizard's Walk among others) just as the Kleenix folks lost control of their brand name. That doesn't mean though that we should ignore that portion of copyright. It is sad to see the tiny revenues, or worse the recognition of composer's efforts, for things like Inisheer, Da Slocket Light, Dark Island, Josefin's Waltz and My Cape Breton Home be denied just because those of us in the trad world pass things around with so little attention to the niceties of respecting the composer. Most of those folks would be happy to give permission (as Jay did to thesession) if they are just asked. Then we can attach their name to the music we pass on with the knowledge that we are respecting the composer.
Don't misunderstand. I think the (US) copyright law is largely set up to benefit Disney, Time Warner, Michael Jackson (if his estate still owns what it used to) and a handful of others to the detriment of the rest of us. But that, it seems to me, is different from being careful in attributing the music of living or very recently dead composers correctly and attending to whatever moral or financial responsibilities we have to respect their work. Have you ever heard Ashokan Farewell introduced as "a famous old Civil War tune?" I have. And it was in a concert of a fine professional group who should have known better. When I pointed it out to them the response was that they knew but didn't think it important. Baloney!
OK, stepping off (very high) soap box and donning flameproof suit!
