Berrygerry- I tend to agree very much so. I just think that British rock bands ran further with the blues influences of the African American original blues artists like Muddy Waters, Howlin Wolf, John Lee Hooker, Robert Johnson from the 1930's and 1940's than most American bands did- and it produced some of the greatest Rock n roll in history because the blues were bigger in Europe and England than over here in America where blues started.
Because of extremely prejudiced views of white Americans towards African Americans especially in the 30's and 40's most American bands tried watering down 1950's music where the be-bop sounded tepid and boring compared to original blues in my opinion. But Elvis Presley, Little Richard, and Chuck Berry owe everything they ever started to those old African American artists of the 30's and 40's. It's like the old expression goes, " The blues had a baby and they called it rock and roll ".
I've just noticed over the years as a musician myself that white rock n roll bands from England give more credit and respect to the blues musicians who started the ball rolling in the 1930's and 1940's. Some groups in America do too- but in England they vocalize that respect more and honor rock n rolls roots
