You have bever been so wrong.
That's like saying Rush Limbaugh is nothing but warmed over Wally George.
Check what was in the charts before the Beatles.
The BEST were The Four Seasons and Bobby Rydell....for God's sake.
Show my any good, much less great, rock album before "With The Beatles". (US "Meet The Beatles")
PS..."Johnny Horton's Greatest Hits" (as good as it was) doesn't count. :-)
So since everything else came afterward, you conclude everything else was derived therefrom?
