I love The Beatles and own just about every one of their original U.K. Parlophone albums. Greatest band of the 60’s. However, I also like late 50’s hard-charging pure rock like Little Richard, Jerry Lee Lewis, etc.... the Beatles actually liked and played Little Richard tunes. Pure ‘50’s rock and roll seemed to be on life support in the early ‘60’s, with Motown and the Beach Boys emerging as two opposites of the same coin. No more “four-on-the-floor” drumbeats like late ‘50’s rock. Folk music, ie Joan Baez and the man who she helped get started (Bob Dylan) etc. were also getting really big by 1963. Without the Beatles, would rock and roll have died out around 1963 and been replaced by Motown harmonies, folk music and surfing ballads?
