Not sure if he's still around, but for the last few years Nick Proudfoot had a song swap group at Harvard for undergraduates. The phone & email I have for him (617) 493 - 5943 proudf@math.harvard.edu If those are obsolete, let me know & I'll try to find him for you. My email is judypredmore@webtv.net I'm probably your parent's age. If I think of any other young people, I'll let you know.
