John, Yoko and their message to their fellow man.

"Imagine" is a utopian-themed song performed by John Lennon, which appears on his 1971 album, Imagine. Although originally credited solely to Lennon, in recent years Yoko Ono's contribution to the song has become more widely acknowledged.

"Imagine" is widely considered as one of the greatest songs of all time. In 2004, Rolling Stone magazine voted "Imagine" the third greatest song of all time. Former U.S. president Jimmy Carter said, "In many countries around the world — my wife and I have visited about 125 countries — you hear John Lennon's song 'Imagine' used almost equally with national anthems."

In the book Lennon in America, written by Geoffrey Giuliano, Lennon commented that the song was "an anti-religious, anti-nationalistic, anti-conventional, anti-capitalistic song, but because it's sugar-coated, it's accepted."
