Sir Ringo Starr

McCartney isn't the only Beatle who doesn't sign autographs, as his Fab Four bandmate Ringo stopped doing so as he was uncomfortable with others profiting from it.

The 85-year-old drummer said back in 2016: "I don't autograph.

"All autographs are on stuff that I've (done). One of my painting or something I'm involved with, and it goes to charity. It doesn't just go out there for other people to sell."
