Feature interview - Did Yoko Ono break up The Beatles?

We know her name, but the story of Yoko Ono has been largely ignored or told only as a footnote in the story of John Lennon and The Beatles. Music journalist David Sheff was the last person to interview Lennon and Ono just before Lennon was murdered in 1980. He's maintained a friendship with Ono over all these years. She's now 92, and Sheff's new book 'Yoko: A Biography' spans her life as the child of wealthy parents in pre-war Tokyo to the avant-garde art world. Jesse asks David the question, did she break up The Beatles.
