Yeah.
And don't forget Bo Diddley, Little Richard, and Fats Domino.
   Bob Dylan always said Little Richard was one of his major influences.
 Without Chuck Berry there might not have been Beatles or Rolling Stones.
  The radio airwaves might still be filled with the likes of Perry Como, Dinah Shore, and the military marches that sent boomers off to school in the 1950;s.

  In an era of puritanical mass conformity and fear of being different, rock 'n roll was about sex, rebellion, danger, and giving black folks their due credit for their amazing contributions to American culture.
   After Elvis was grabbed by the army, he lost his mojo. When he was co-opted by Hollywood he didn't rock much. When he started playing Las Vegas he was done.
   Today rock 'n roll isn't dead but it's weak. Time has proved, no rebellion = no rock 'n roll. And we are all the poorer for the timid tenor of the times
