Jerry Lee Lewis is a famous piano playing rocker/country star of the 50's, famous for his over the top way of playing the piano, including using his feet. He got in trouble for marrying his cousin who was underage.
He is the cousin of Mickey Gilley AND the infamous Jimmy Swaggert. They all took piano lessons from their grandmother.
Thanks, my mother would have kicked my butt if I played her piano with my feet. Anyway, thanks for the information, but I don't even know who the other two people you mentioned are.
