“Stop right there,” he reportedly tellsThis Cultural Life.

“I am not the person who instigated the split.

Oh no, no, no.

John walked into a room one day and said I am leaving the Beatles.

Is that instigating the split, or not?”

“So for a few months, we had to pretend,” McCartney explains.

(According tothe Telegraph, a judge agreed with McCartney’s argument and legally divided the band.)

And they thanked me for it years later.

But I didn’t instigate the split,” McCartney says.

“That was our Johnny coming in one day and saying ‘I’m leaving the group.'”
