On June 1, 1969, in room 1742, in “Queen Elizabeth Hotel”, in Montreal, Canada, John Lennon and Yoko Ono recorded the song “Give peace a chance”. The song was written by Lennon and recorded by André Perry, using a simple setup of four microphones and a four-track tape recorder. Lennon played acoustic guitar, accompanied by Tommy Smothers from the “Smothers Brothers”, also on acoustic guitar. The recording session was attended by number of journalists and celebrities, including Petula Clark, Timothy Leary, Rabbi Abraham Feinberg, Joseph Schwartz, Rosemary Woodruff Leary, Dick Gregory, Allen Ginsberg, Murray the K and Derek Taylor. The song was released as a single by “Plastic Ono Band” on July 4, 1969 (UK), on “Apple” label. “Give peace a chance” became an anthem of the American anti-war movement during the 70’s.
