It was composed on a Steinway piano in a bedroom at his Ascot mansion, Tittenhurst Park. Yoko Ono stood by while he created the music, chords, and majority of the lyrics, practically finishing the entire song in one quick writing session. Lennon started working on "Imagine" shortly after he heard Nixon declare his re-election campaign slogan as "I am not a crook." He felt this indicated that people were still thinking about world peace and thought songs could help spread messages about important issues. He also wanted to create a song that would appeal to both adults and children. Imagination was chosen as the title of the album because it was easy to remember and described what everyone is trying to do with their lives: imagine peaceful times and communities where there is love and hope. Lennon wrote "Imagine" in one sitting, beginning around 2:30 PM and ending nearly three hours later. He then went back and edited the song down to its present length of 3 minutes 40 seconds. Yoko Ono has said that she was not involved in the creation of "Imagine", only helping out with some of the lyric changes. She decided to become more active in the production process after hearing how much money the two had made together selling albums of her artwork. Lennon first performed "Imagine" on television during an interview with David Frost on October 30, 1971.
