A personal Christmas favourite, Happy Xmas (War Is Over) was originally released on 24th Nov 1972 (Dec 1971 in the U.S.) by John & Yoko The Plastic Ono Band with the Harlem Community Choir, and reached #4 in the UK. However, following Lennon's death on 8th Dec 1980, it was re-released on Dec 20th 1980 and reached #2. The song was intended to be released in 1971 but a publishing dispute delayed this by one year.
The protest song about the Vietnam war was a non-album single, and was written by John Lennon and Yoko Ono. It failed to chart in the U.S.
