Paul McCartney has kept a packed touring schedule in recent years, but the 74-year-old Beatles legend says he may need to slow down soon.
Asked by Rolling Stone magazine if he could imagine touring in the same way at 80, McCartney replied: "Unimaginable, and unseemly." But McCartney added that, when he was 17, he thought a 24-year-old at fellow Beatle John Lennon's art school was old.
"People say age is a number. It's a big number the older you get," he said in the interview published on Wednesday. "But if it doesn't interfere, I'm not bothered. You can ignore it. That's what I do," he said.
McCartney recently said he was drinking heavily and almost quit music after The Beatles split in 1970. But he has embraced touring with renewed vigour in recent years, playing with only occasional months-long breaks since 2009. He remains one of the world's biggest concert draws.
McCartney's latest global tour culminates in October at California's Desert Trip, a one-off mega-show that will also feature The Rolling Stones, Bob Dylan, The Who, Neil Young and Roger Waters.
