Ringo Starr and John Lennon always had a close friendship. They were the two oldest Beatles members, lived as neighbors, and hung out together after the Fab Four fractured. The drummer was the last Beatle to see John before he died, and Ringo was blown away by his mindset at the time. Years earlier, John’s singing freaked out Ringo, and we understand where the drummer is coming from.
The Beatles split up in 1970, but that didn’t prevent the former bandmates from working together. Ringo played drums on George Harrison’s All Things Must Pass in 1970. He sat at the kit for John’s John Lennon/Plastic Ono Band solo debut the same year. Though used to recording with the bespectacled Beatle, some of John’s behavior in the studio freaked out Ringo, he writes in Postcards From the Boys:
“I can say this now (if he was here, John could tell you), but suddenly we’d be in the middle of a track, and John would just start crying or screaming — which freaked us out at the beginning. But we were always open to whatever anyone was going through, so we just got on with it.”
