Sir Paul McCartney considered hanging up his bass and retiring from music when he reached the age of 50.
In the early 1990s, the Beatles legend agreed with a manager who told him it was time to walk away from rock 'n' roll because he was getting too old.
But the rocker changed his mind after realising he still loved playing music - and he fired the aide instead.
MCCartney tells Mojo magazine, "One of my old guys who I used to have as my manager, I was knocking 50 and he said, 'I think it's time you retired.' I thought, 'I know what you mean, s**t, but I don't feel like it, you know. And if I'm really enjoying this, why retire?'
"So I decided against it, and got rid of him. I wonder what he thinks today. Perhaps that he was right, but hopefully not."
