What I see hear is the continued miss information first stated by Keith Richards during an interview for the movie Hail, Hail Rock N Roll. Here's a few things I guess some just don't realize. Chuck Berry sang in the children s group at Church, his sister Lucy was an aspiring Opera singer, his sister Thelma was an accomplished piano player as was their mother, he played the piano AND saxophone. What Keith overlooked was Chuck's background and what he listened to in his youth. Chuck grew up during the blues, country, boogie woogie and big band era of the 30's and 40's. What keys were the big band and boogie woogie bands using at the time, primarily HORN and PIANO keys! With him being a piano, sax and guitar player, listening to Charlie Christain, Carl Hogan and T-Bone Walker by default he played what were the keys of the big bands. Tommy Dorsey's band had a guitarist, but the guitar was nearly relegated to a filler position since it was an un-amplified instrument at the time. Did Johnny Johnson have an influence on the music? Of course he did just like Otis Spann, Lafayette Leek and Fred Below. What would be very helpful for some of you would be to listen to the session tapes in the BOX set and hear the interaction between the Chess Brothers and band. Ninety percent of it is directed toward Chuck Berry. You will also hear Chuck himself directing the other band members as to what to do. James Brown was the same way and even more so. He had absolute control over all the iterations of his band. Maceo, Fred, Bootsy, Catfish you name it, it was James Brown laying down the beats and humming the rhythms.
