Black and white image of John and Yoko kissing, with white text on a black background
Yoko Ono met John Lennon, member of The Beatles, in 1966 during a preview of Ono's art exhibition at a London gallery. They began an affair a year later and married in 1969. In addition to collaborating on numerous recordings, the couple held "Bed-ins for Peace" to protest the Vietnam War. It is rumored that Yoko Ono's relationship with John Lennon was the cause behind the breakup of The Beatles.
