What is generally regarded as the first rock 'n' roll song was about rock:
Rock Around the Clock - Bill Haley and the Comets (You Tube clip)
Uh, do you know what "Rock" meant in the 50s?
How about Rock and Roll by the Velvet Underground?
Then, one fine mornin', she puts on a New York station
You know, she couldn't believe what she heard at all
She started shakin' to that fine, fine music
You know, her life was saved by rock'n'roll
