But then again, Elvis imitated Hank Williams et al and all of the black musicians he heard late at night when he could pick up those Chicago and Memphis radio stations. As for Chuck, he was a rytmym and blues man long before he and Little Richard kicked up the tempo, cleaned up the lyrics and told the white kids about rock n roll. All music is derivative.......but as previously stated by many, the guys in the 60's and 70ls took the music to new places. It also didnalt hurt that many of the players (Clapton, Beck, Hendrix, Allman, 6reen, etc) were considerable more polished and proficient musicians than there idols, although I will admit that a few, like Magic Sam, Freddie King, Otis Rush and Buddy Guy could hold their own. But if you think about, their later playing got louder and more distorted after they heard those you Brits play their songs.
