Was on this show, the Mike Douglas Show-- but it wasn't this time. I'm guessing by Sonny and Cher's disco hairdoos that this is during the same period though, a no-man's land after his late 1960s boomlet and before he struck it big again with the London Sessions. He has a sad, "why am I here?" affect that might explain why, when I first saw him on Mike Douglas and Dick Cavett, I was interested but not really affected. It took a live show (even sadder-- but definitely compelling) to get me drawn in, and it took the original records to make me a fanatic. Once I heard those it was all over. But Chuck Berry kept working through thick days, and the thin ones like this. (I'm sure I saw this. I saw him on Mike Douglas several times before the famous John Lennon show.)
I'll say this for Mike Douglas-- he was a nice guy, and he had a lot of really great musicians on his show. I saw Chuck Berry on that show at least four or five times, including the big one with John Lennon,and I saw B. B. King there, too. Good thing about Mike Douglas-- he talked to his musical guests as if they mattered.
