Never been an autograph or memorabilia collector, but I do still have my right hand which shook Bob Dylan's at the old New Haven Arena in 1966 when I was 17yrs old. My buddy and I went up to the side of the stage as the first set was ending and Bob was walking off. I reached up my hand and he took it and gave it a little shake.
That show still ranks as one of the best I've ever been to, being one of Bob's earliest electric shows. I remember that he had a lot of trouble navigating around the stage with all the guitar cords that he wasn't used to having there. Tripped and almost stumbled a few times. Saw him again that same year in Hartford at the Bushnell.
