I don't play Guitar because, back in the late 60s I sat about 5 feet from Stefan Grossman(at Les Cousins in Greek st London) and watched him play Dallas rag and realised 1 I could never play like that, 2 I had not the patience or dedication to try.
I "revisited" his recording of it last night and it still amazes me and I still dont know how he does it without an extra digit on each hand!
