It's just when they did stadiums and the technology just wasn't there to justify those performances, andthe Beatles indeed not able to hear themselves over the screaming girls, who really probably weren't even sure what those guys were playing or cared honestly.
But, by 1968 (Monterey Pop Festival), and surely by Woodstock (August 1969), all of the Beatles had to know that their was ample amplification available for any band to overcome crowd noise for a Rock'n'Roll show.
But, The Bealtes, before they split up, still chose not to go on the road, even for a limited set of dates. That was their choice.
But only
after breaking up, all of the Beatles chose to tour.
I was making plans to go and see my first Beatle in concert, until that psycho Mark David Chapman murdered John Lennon, a loving father, and a loving husband. I hope that C/S Chapman never gets paroled!!!
