"And he does it all without looking!" ...and not looking may be one of the keys to his speed and precision. I watched, thru binoculars, Doc, Norman Blake, Dan Crary and Tony Rice play together at Winfield in 1972 or so, and noted the flying fingers on the left hands...except for Doc! His fingers raised just enough to clear the strings, then were on to the next note. I guess when you can't see, the less distance to navigate, the better!

Anyway, he is a consumate *musician* and I'm glad I saw him several times.
