Paul McCartney: What Is The "Beatles" Legend Doing Today?

Paul McCartney is keeping busy despite being in quarantine amid the COVID-19 pandemic. He's currently scheduled to headline the One World: Together At Home COVID-19 benefit concert on Saturday, April 18.

But first, on Tuesday, the former Beatle had a call-in interview on The Howard Stern Show on SiriusXM. With Stern, he discussed The Beatles, John Lennon's departure from the band, and George Harrison's abilities as a songwriter during the run of The Beatles.

Stern questioned McCartney about why the band didn't continue after John Lennon left in 1970. The host's angle suggested that McCartney didn't want to go on because he undervalued the contributions of George Harrison and Ringo Starr.

McCartney insists that that was not the case, however.

"I hear what you're saying, but the thing is, Howard, [a band]'s like a family. When families break up, it's to do with the emotion and the emotional pain," McCartney explained.

"You're hurting too much, and so it wasn't going to happen. We'd been through too much and I think we were just fed up with the whole thing."

But the now 77-year-old McCartney did agree that everyone had overlooked Harrison as a Beatle.

"It was easy to underestimate George because me and John, like you said, had always written most of the stuff and it had most of the singles," McCartney said.

"George was a late bloomer, as far as writing was concerned. He wasn't that interested in the beginning. But then he started to get interested — and boy did he bloom. He wrote some of the greatest songs ever."

McCartney and Stern also shared their fondness for the Harrison-penned track, "Here Comes the Sun," from Abbey Road.

McCartney and Harrison both enjoyed successful solo careers after the break-up of the Beatles, but they and the band didn't reunite. Lennon was later murdered in 1980.
