For me you can't beat those shows from the days I first saw Chuck Berry. My first show was February 1971. Here he is 20 months later, enjoying the thrill of victory after The London Sessions. I'd see my last 1970s show about a year and a half later. When I see performances like this, all the elements that drew me in are there. And you've got to admit-- the practice of constant touring made him pretty perfect in those days!
By the way, it wasn't 1973. I figured that out a long time ago but forgot. It was December 1972.
