I'm just listening to Sketches now and I think it's such a shame he didn't do more stuff.

I think I own all his commercial releases apart from the 1991-1992 compilation of songs he did with Gary Lucas (is this good?).

What I'm really after is someone to tell me there is a lost treasure trove of great bootlegs out there. Are there? Were there any other outtakes from Grace / Sketches that haven't been released? Are there any songs he did live that haven't appeared on some release? Is there any way of getting hold of these if so?
