My "who cares?" (which could probably have been better worded as "does it matter?") was a direct answer to your question "would anyone else want to watch/listen?". As in, do things necessarily have to be played purely because other people will want to listen to them?
Personally, I'd give my left nut to have his level of skill, both in playing and transcribing. He obviously has an amazing ear as well as 'awesome chops' as I believe some of the hep cats say. Or used to, last century.
