Sorry, but this was the landmark record that started it all...before Elvis, before Pat Boone - a former country & western group that took the R&B back beat and changed face of pop/rock music.
Bill Haley and His Comets are always given the shaft when it comes to their important influence on rock and roll. Haley began his career in the mid-1940's, and was cranking out some excellent rockabilly stuff on the Essex label when Elvis was still in high school in the early 1950's.
Bill Haley & the Comets had the big hit on "Rock Around The Clock" in May of 1955 but they also "covered" the song that was first recorded by Sonny Dae, a black artist.
