Do you think if this was really so, as it provocatively suggests Danny Boyle in his latest comedy Yesterday. Think about it if Paul McCartney it arrived in the studio at Abbey Road, he had tried to listen to his new song Let it be to the other three, and none had listened to him. Maybe McCartney would let lose, maybe that song only hinted that he had made to hear for the first time to the other during the sessions for the White Album in 1968, the Beatles would never engraved, maybe he would have realized later, with the Wings (as ironically suggested that Lennon, after the end of the band). And we would not have what is now, universally, it is considered as one of the masterpieces of the repertoire of the beatles.
