I don't know about the ethical stuff - I wouldn't think it could be copyrighted - just a discussion list, but what do I know? I would be happy to post what sounds interesting. Not long ago they were doing a riff on the little bits of doggerel people have made up to go to classical themes (eg - "kill the wabbit, kill the wabbit, kill the WA-bit!") - reminded me of the parodies posted here! (Who sez academics have no sense of humor?) If something comes up, I'll post it under an ethnomusicology heading.
