Before Yoko, John was definitely the leader of the Beatles, he was the one who pushed them, definitely the strongest personality of the band.
After Yoko, it seemed he didn’t care at all about the band, and that’s when Paul took over.
In any case, just as John and Yoko ended war and brought peace to the world though their brilliant collaborations in the late 60’s/early 70’s, I am certain Yoko’s new album
of sounds like a chattering monkey will lead to world peace in our time. /s
