Never saw him in concert but I did see him in Chicago. One day I was walking down Wabash towards the Kroch & Brentano's bookstore which I always liked to visit after getting off the South Shore Train. A limo pulled up in front of the store just as I got there and a well dressed gentleman came out. I thought he looked familiar and then I went inside there was a book signing table set up for Chuck Berry. I wish I had bought a copy. I knew some of his work but wasn't really knowledgeable. Years later I saw the documentary Hail,Hail Rock and Roll and wish I had bought that book.
