I am really glad to hear that so many people came to appreciate Butterfield over the years. I really did not understand what I was hearing,but I thought it was fantastic. No one made much fuss in those days.I was always rather impressed by the improv Butterfield and Bloomfield did on some songs,some nights. Actually many of these live performances were much better than the recordings.I really enjoyed watching Mike Bloomfield,who had a good time. They would have considerable time between sets,so they were in the back room for long waits;I thought they were all very nice to Big Joe Williams and me. It was pretty relaxed back then.
