Bob, just to clarify the "demo" incident. That was in 1993 when I went back to college for the IT degree and took music classes to have more credit hours for my grant. The offender was a 19 year old kid who thought he could cheat his way into an A. In my mind had I let him get away with it, that would have devalued my A. (And I take that seriously as while going through a BA program in 3 1/2 years and the AS in 18 months I never had anything BUT an A.) That class met Tuesday and Thursday. He made "his" presentation Tuesday. On Thursday I asked if could present a composition and played the exact thing he did Tuesday. The prof asked "Didn't we just hear this on Tuesday?" I said "Yes. It's the demo song in a Yamaha DX7."
So it wasn't an elder who dud that. In 1993 I was 42 and he was 19. And lazy. And a cheat. Had I met busted him he would have cheated his way into an A.
