When I was growing up in a little Oklahoma town, white people lived on one side of the tracks, literally, and black people lived on the other. The black folks had a dance hall for Saturday nights. Bo Diddley used to play there from time to time. We white kids were scared to go there, but I sure wish I could have heard him in his prime. The rhythm ‘n’ blues man who turned the guitar into a percussion instrument and helped invent rock ‘n’ roll died at age 79.Here he is from around that time in 1966. Notice that in the crowd whites are one side and blacks are on another, but it is the white teenagers who are really going wild at this sound.
