Umm Elvis?
good point, but he wasn’t quite as big. close tho. of course elvis was more establishment than the beatles, which is one reason why they were hyped and foisted upon the world as much as they were. now i wasn’t an elvis fan until after he died, so i may be a tad biased, but i think in total he was close, but not quite. he served in the military (iirc) while the beatles were anti war.
not trying to change your mind, just explaining my position.
