Paul McCartney reveals explosive 'f--- you, John' moment after Beatles lawsuit

Paul McCartney revisited one of the most contentious chapters of The Beatles' history in "Man on the Run."

McCartney defended his decision to sue The Beatles and revealed the "f--- you, John" moment that came after in the documentary chronicling the end of an era and the beginning of the singer's journey with Wings. But before creating Wings, McCartney dealt with the fallout of The Beatles' breakup. The band's original manager, Brian Epstein, had died, and arguments over who should be hired had hit a fever pitch.
