As the Vietnam War raged in 1969, John Lennon and his wife Yoko Ono held two week-long Bed-Ins for Peace, one in Amsterdam and one in Montreal.
Each Bed-In a non-violent protest against wars, and experimental tests of new ways to promote peace. The idea is derived from a “sit-in”, in which a group of protesters remains seated in front of an establishment until they are evicted, arrested, or their demands are met.
The public proceedings were filmed, and later turned into a documentary movie. The film Bed Peace was made available for free on YouTube in August 2011 by Yoko Ono, as part of her website “Imagine Peace”.
