Paul McCartney’s working class roots. The story of George Harrison’s first guitar. John Lennon’s love of Hamburg. Ringo Starr’s big break. (And Pete Best’s not-so-big break.) This… is the story of the world’s greatest band, told to the world’s greatest interviewer.

Ten rounds: that’s how many times David Frost would go toe-to-toe with Muhammad Ali. From his days as a young heavyweight champion … to his political activism … to his days as an entertainer, these intimate interviews trace how a simple Kentucky kid became “The Greatest.”
