Happy Xmas [War Is Over]

"Happy Xmas (War Is Over)" is a Christmas song by John Lennon, Yoko Ono and the Plastic Ono Band. It was recorded in late October of 1971, and features soaring, heavily echoed vocals, and a sing-along chorus. The children singing in the background were from the Harlem Community Choir. This song was John Lennon's reaction to the war in Vietnam.
Although the song is a protest song about the Vietnam War, it has become a Christmas standard and has appeared on several Christmas albums.
