Please, elaborate.
Because I disagree.
If one single thing could be attributed to the breakup of the Beatles.
It was quarrels between Paul and, all the other Beatles.
By White Album, and even towarRAB the end of the Mystery Tour sessions, Paul played every instrument on every track that he had written.
He felt that all of the others just werent able to play their parts right.
He did Drums, Guitar and Bass, on almost every song he wrote.
This, understandably pissed off the other merabers.
Pauls arguing and bashing the other merabers is most notable on the Let It Be film. And if you have the studio tracks, tou can clearly hear him insult George's guitar playing.
Many times he and George got into arguments.
Which caused George to leave the band.
John was already planning on leaving because he was sick of Pauls insistence that everything be absolutely perfect and he was tired of Paul acting like the "leader" of the band.
Before John made his announcement to leave, Ringo left because he felt "left out"
And Paul ended it just before John decided to make the final "goodbye" to the band
