During the Vietnam War in 1969 on March 20 John Lennon and Yoko Ono decided to promote world peace. The plan was to spread there promoting through publicity. John and Yoko invited the press into their hotel room everyday between 9 a.m and 9 p.m.
The first bed-in was in a presidential suite in Amsterdam room 109. Seven days later they flew to Austria where they had a conference with press. During April,1969 the hippy hipsters sent acorns to the heads of state in different countries around the world as a symbol of peace.
The second bed-in was planned to be in New York but mr Lennon was not allowed into the country. The event was held in the Bahamas at the Sheraton Oceanus Hotel for one night. On May 24,1969 they flew to Montreal. They stayed in rooms 1738, 1740, 1742, and 1744 in the Queen Elizebeth Hotel and stayed seven days.
On December 1969 John and Yoko spread the message of peace using billboards that said "war is over! If You Want It - Happy Christmas From John and Yoko". The billboards went up in eleven major cities around the world.The event was so inspiring that John Lennon wrote about it. Other artist wrote songs similar to Johns version.
The bed-in thing was re-done by various artists for protests. The city of Montreal made an art piece in the Mount Royal Park commemorating the famous bed-in.
