I felt I wasn’t playing great, and I also felt that the other three were really happy and I was an outsider.

I went to see John, who had been living in my apartment in Montague Square with Yoko since he moved out of Kenwood. I said, “I’m leaving the group because I’m not playing well and I feel unloved and out of it, and you three are really close.” And John said, “I thought it was you three!”

So then I went over to Paul’s and knocked on his door. I said the same thing: “I’m leaving the band. I feel you three guys are really close and I’m out of it.” And Paul said, “I thought it was you three!”
