Lennon and Ono met in London in the mid-60s and married in 1969, about a year before the Beatles broke up. The couple made headlines protesting the Vietnam War by holding “bed-ins,” creating the idea of “bagism,” and recording “Give Peace a Chance" as the Plastic Ono Band.

Lennon wrote about the relationship in the song, “The Ballad of John and Yoko.”
