Paul McCartney on restoring his friendship with John Lennon after The Beatles’ break-up

Apart from the visits, Sir Paul would have regular chats on the phone with John.

He said: “We would talk on the phone…we had some great ordinary conversations that were very sort of endearing.”

Their conversations could be as normal as talking about baking bread at home, which saw them both exchange recipes with each other.

The 78-year-old remembered: “It was lovely, this was how it had been when we met with just a couple of guys chuntering on about insignificant stuff.”
