A reformed Nirvana lineup went on to perform the song with The Beatles legend at the 12-12-12 Hurricane Sandy benefit concert.
"We walked in; we jammed the song. It just came out of nowhere. The best songs happen that way," Grohl told KROQ. "We recorded it live and put a vocal over it and that was it. It was three hours and it was perfect."
"One of the great things about playing with Paul McCartney or playing with Neil Young is that that generation of musicians, they cherish and respect and value the practice of just going into a room and coming up with something and jamming and making it a song," Grohl added. "There’s not like seven songwriters and seven producers and digital technology or whatever. It’s like people getting in a room."
