Recently, Paul McCartney went on recall to The Express the last time he saw Lennon: “I was at John’s place and Saturday Night Live was on and John said to me, ‘Have you seen this?’ I hadn’t, I was living in England, he was living in America. He said,
‘No, they’re offering us money to get back together — Lorne Michaels came on the show last week.’ And John said, ‘We should go down, just you and me. We’ll just show up. There’s only two of us, we’ll take half the money.’ For a second we were like, ‘Shall we do it?’ I don’t know what stopped us. It would’ve been work and we were having a night off so we elected to not go to work. It was a nice idea. Wenearly did it.”
