Yeah Tinpan, a shame about Neil Young. I'm guessing he'd be quite high up the GT list of artisits to teach but I'm also guessing that they are unable to negotiate terms for the copyright. As amazing as Neil is, he does give the impression that he is pretty cantankerous when it comes to commercial entities profitting off his music etc. Not sure if he holds all the copyrights to his music, but probably does and probably wouldn't be easy to deal with.

Shame.
