John Lennon, Yoko Ono, and Chuck Berry perform "Memphis" (1972)

In February 1972, John Lennon and Yoko Ono were guests hosts on the Mike Douglas Show. Here is John and Yoko with Chuck Berry performing "Memphis, Tennessee." Watch for Yoko's yodeling (I know, primal screams) and Berry's big-eyed reaction at 1:19 in the video. What fun! (via John Curley)
