Chaos Is a Friend of Mine

I want to point out the complex relationship between American electric blues, rock and roll, and the British invasion. The Rolling Stones site blues musicians like Robert Johnson and Muddy waters as major influences to their sound. The Beatles site Chuck Berry as a major influence as well. In the Bob Dylan interview titled "Chaos is a Friend of Mine", Dylan explains that the English are responsible for bringing this sound into the mainstream. To what extent do you think Rhythm and Blues owes its popularity and economic potential to the British invasion? Also in the early 60's, as English artists are starting to make money off this sound, what kind of success are black blues rock artists seeing?
