Back in 1980 Lennon mentioned: “That was a interval when Paul simply saved turning up at our door with a guitar.
“I’d let him in, however lastly, I mentioned to him: ‘Please call before you come over. It’s not 1956, and turning up on the door isn’t the identical anymore. You know, simply give me a hoop.’”
Lennon went on to admit: “He was upset by that.”
Despite this, he added: “But I didn’t imply it badly. I simply meant that I used to be caring for a child all day, and a few man turns up on the door.”
