It was John Lennon who taught the world that “all you need is love”—he just didn’t say how much you need. After marrying his first wife, Cynthia, in 1962, Lennon began an affair with Yoko Ono in the late 60s. In 1968, while Cynthia was on a holiday in Greece, Ono visited Lennon at his estate and the two recorded the album Two Virgins in one night. “It was midnight when we started Two Virgins, and it was dawn when we finished, and then we made love at dawn,” Lennon recalled. “It was very beautiful.” Though perhaps not for Cynthia, who walked in on the pair sitting on the floor in bathrobes, staring at one another. Lennon ended the marriage that year and wed Ono in 1969. The two remained together until his death in 1980.
