What would Picard do?
There was a lot more to it than that. After John's remarks about the Beatles being bigger than Jesus the whole thing had become a bit of a circus, with the KKK making death threats, and demos outside venues, many venues not even coming close to selling out. The Beatles also felt that as musicians they were going backwards - that ties in with not being able to hear themselves at gig, and then they very nearly got themselves arrested in The Philippines, death threats in Japan, and John had been offered a part in a film - all this with inevitable tensions between the band members which came to a head a year or two later during recordings of Sgt Pepper and The White album.Well, they gave up because they'd got sick of not being able to hear themselves play, goes the story, due to screaming drowning out the crappy sound systems they had to employ in venues far too large for normal PAs. This led to more experimental stuff in the studio they probably couldn't reproduce live and which was more exciting than playing 200 times a year.
In a way the band really should have come to a natural end after '66, but McCartney suddenly stood up as the leader to keep the band together, while John became despondent and uninterested much of the time.
