I saw Doc and a very young Merle in 1962 at the Ash Grove in Hollywood. We sat in the front row just so I could copy some of his moves. HAH!! Fat Chance !! I have never seen fingers move so fast - his flat picking seemed like it was in slow motion until you put the visual and the aural together. About halfway through the second set, Doc announced that he had just heard there was a very special guest in the audience and introduced Leslie Keith, an old time fiddler from his neck of the woods. He got him up on stage and they did three numbers -- fiddle numbers -- an unbelievable night and one I'll never forget.
