The piano which John Lennon used to compose the song 'Imagine' sits on the grassy knoll next to the site where former US President John F. Kennedy was assassinated on this day in 1963 in Dallas, Texas November 22, 2006. The piano, which is now owned by musician George Michael, is being shipped to different locations to be photographed as part of a specially curated photo exhibit to promote world peace. In the background is the former Texas School Book Depository from where Lee Harvey Oswald is believed to have fired the fatal shots that killed Kennedy. REUTERS/Jessica Rinaldi (United States)
