Buddy Holly was intentional Rock and Roll. Bill Haley always struck me as an anomaly or an accident. The Comets was a C&W dance band who sort of stumbled into Rock and Roll and really never belonged there.
"Surfin' USA" was a copy of "Sweet Little Sixteen" musically, though the lyrics were prototypical Brian Wilson. Chuck Berry's plagiarism lawsuit threat was settled out of court. It's really sad because Carl Wilson was patterning his guitar playing directly on that of Chuck Berry.
--- Thanks a lot the info Batgirl. Yes of course " Buddy Holly & The Crickets " belong in a class of their own without a doubt, however " Bill Haley & His Comets " also go way back to the early days of Rock. Plus there is also a connection between Rock and Country music thru " Rockabilly Music ". That reminded me of the fact that Elvis Presley had his big early hit ( back in 1954 ) with " That's All Right Mama " and also had his version of " Blue Moon Of Kentucky " on the same 45 rpm record. Of course Bill Monroe of Bluegrass fame had written " Blue Moon Of Kentucky " and when Elvis recorded that number he had to speed up the tempo a bit.
Thanks for the new posts and the info.
