I never knew about that! I remember Alan Freed (also Murray the K and his Swinging Soiree) so long ago, when I was a kid with a father who was a rock and roller and a plastic radio on my nightstand. But this trick on Chuck Berry I wasn't told about.
I liked Jerry Lee Lewis and had all the records, but mom didn't like him. (cradle-robber) Regardless of that, I have to say that stunt of Lewis's was shameful, childish and vain to the Nth degree. Chuck Berry was a genius in his time, and did not deserve such treatment.
I did enjoy learning about this episode though, and the video. Thanks, Meanderer!
