Yes
The term "rock and roll" and "rockin it" go back to early R&B. Later on in the 1951 rock and roll was re-introduced as a sanitised version of this with the sexual themes removed to make it safe for white people to listen to on the radio. Alan freed was the first white man to popularize this genre of negro music for radio and he helped make rock and roll a household name.
