Very interesting article.

I have never been a fan of Yoko Ono's art or singing. That being said, once I became an adult with adult relationships, I also completely rejected the idea that Yoko Ono broke up the Beatles, any more than some guy or girl "broke up" someone else's relationship/marriage.

Ringo, Paul, John and George had agency. Their relationship as a band was theirs. If Yoko was disturbing Paul or Ringo or George in making music with John as "The Beatles" then they could have (and maybe did) discuss it the John. If John said, "I don't care, I want her there" then it was John's decision. If the other three couldn't work with her there but didn't open their mouths, that was their decisions.

You describe Ono as "another piece of studio gear." Do you blame the piano in the studio for breaking up The Beatles? Of course not. That would be ridiculous. It is just as ridiculous to blame Yoko Ono.

Most things I've read have said roughly the same as you write, that the Beatles were nearly worn out as a group by the time Yoko Ono came on the scene. It is IMHO just a sad statement on our misogynistic culture that when something interpersonal happens that we don't like, we often try to find a woman to blame.
