That was the point, they borrowed from many genres and not only became unique, they had an edge that many of us found to be a nice foil for the jingle playing, clean cut Beatles!

Still, i grant you that many English musicians tried to do blues, and it didnt cut it. Eric Clapton would give his left nut to have been an American Blues Player!

"Missing the mark" of any of those (think "limiting") categories might suggest the possibility of a less limiting yet distinct quality; the term that would apply ~ "sui generis" (Latin for “of its own kind” anything that is peculiar to itself, of its own kind or class). Also, think a combination of those genres (where the collected sum is greater than the parts). Many British bands were inspired by US blues & Black artists, feeling an identity with their own put-upon working-class consciousness. Things were very tough in post WW2 UK; it was almost as bleak & broke as Germany. Americans don't realize how many things taken for granted were luxuries until relatively recently ~ central heating & having a refrigerator. People lined up for rationed coal well past the war's end. The poor were taught to "know their place" & "carry on" ~ saluting the Queen. Adults had bicycles ~ out of necessity, if they were lucky.

"'Credo Quia Absurdum?' Latin references evidence a desire to be perceived as Intellectual, FOOL!" Mr T.

@@Skipjack7814 I'd say " touché" but quoting Mr. T, really? I am what I am, said Popeye the sailor man; that you "perceived" me as a wannabe intellectual & responded with some (more obscure) Latin is odd. Actually my comment borders on the didactic, giving an explanation, which I suspect rankled you enough ~ to reply. I'll go out on a pedagogic limb; Carl Jung said what irritates us in others is a quality in ourselves.
