Legality recapitulates infinity
I have this funny approach to copyright. I earn my living by it. I've asked Webmsters to take my copy off their site when they haven't paid for it. I defend to the death your right to own your copy and to choose what you do with it. But death (yours) is where I think the right stops. Copyright in perpetuity is stifling. So if you see the story that the copyright in works previously assumed to be out of copyright that have been revived or creatively edited by modern musicologists rests with those musicologosts is all good news (and I'm the first to agree that the record companies rip everyone off (equal opportunity capitalists), do me a favour and go and read Spider's Robinson's Melancholy Elephants (for free no less).
