This week in 1969 John Lennon's Plastic Ono Band "Give Peace A Chance" entered the American singles charts on its way to #14.
The song was recorded at The Queen Elizabeth Hotel in Montreal, Canada, in Room 1742 during his and Yoko Ono's second bed-in for peace. Lennon used the phrase "All we are saying is give peace a chance" during an interview on the first day of the bed-in. He wrote a melody and lyrics over the next few days and recorded the song during the final day of the event.
Lennon and The Smothers Brothers' Tommy Smothers played acoustic guitars, a wardrobe door was repeatedly opened and closed to provide a rhythm and various assembled guests sang during the choruses including LSD Guru Timothy Leary and his wife Rosemary, Poet Allen Ginsberg, Singer Petula Clark and Radio Disc Jockey Murray The K. Also present were members of the Radha Krishna Temple who sang and played percussion. Watch video the performance here.
