I was at his concert at the Fox Theater in Atlanta in 1980! Best concert I have ever been to as well. I even went to the record signing he had at the Turtle Records store in Hapeville the night before. I remember he was much shorter than I had imagined. He was laughing and carrying someone's baby on his shoulders as I came in. I was too broke to buy an album, and therefore I didn't get his autograph, but it was delightful just being there with him.
