Sir Paul McCartney is a living rock legend.

He can pull off seemingly anything behind a microphone with a guitar in his hand — except play himself in the videogame “The Beatles: Rock Band,” that is.

“I can’t play it, that’s the trouble,” McCartney told Jimmy Fallon on Wednesday’s “Tonight Show.” “Are you kidding? It’s very hard.”

“My grandkids play it, and they kill me every time,” he continued. “But I say, ‘But I wrote it.'”
