Since writing his first song at the age of fourteen, Paul McCartney has had an impossibly prolific and singularly influential career. In the 1960s, Paul changed the world forever with The Beatles. He didn't stop there, continuing to push boundaries as a solo artist, with Wings, and through collaborations with numerous world-renowned artists. He has received eighteen Grammys, and in 1997 was knighted by Her Majesty the Queen for his services to music. Paul's most recent album, Egypt Station, was his first one to debut at #1 on the Billboard charts.

Paul is a dedicated philanthropist, passionately advocating for many causes, including animal rights and environmental issues. He's also a very proud grandfather.
