The Foo Fighters star spoke of The Beatles' impact on his life with Access Hollywood at the 2012 MusiCares benefit on Saturday when Sir Paul McCartney was named the organisation's 'Person of the Year'.
"When I was young, that's how I learned how to play music - I had a guitar and a Beatles songbook," he recalled. "I would listen to the records and play along. Of course, it didn't sound like The Beatles, but it got me to understand song structure and melody and harmony and arrangement."
Grohl added: "I never had a teacher - I just had these Beatles records… Even in Nirvana - the Beatles [were] such a huge influence.
"Kurt loved The Beatles because it was just so simple. Well, it seemed simple… they sound easy to play, but you know what? They're f**king hard."
Grohl was able to perform with his idol McCartney at the Grammys finale on Sunday (February 12), which also saw the Foo Fighters star trading guitar riffs with Bruce Springsteen and Joe Walsh.
Foo Fighters won five Grammy Awards at Sunday's ceremony. They took home the 'Best Rock Performance' for 'Walk' and 'Best Rock Album' for their latest release Wasting Light.
