Bed-In for Peace
Beatles legend John Lennon married his second wife Yoko Ono on March 20, 1969. Five days later, in lieu of a traditional honeymoon, the couple holed up in the bed of the Amsterdam Hilton's presidential suite, welcoming media for a week straight to display their deep opposition to the Vietnam War. They followed up a couple months later with another bed-in at a Montreal hotel, where Lennon and a group of supporters recorded the song "Give Peace a Chance."
