Answer 1

Happy Xmas (War Is Over) is a song that was written by John Lennon with partial help from Yoko Ono. It was recorded at Record Plant Studios in New York City in late October of 1971, with the help of producer Phil Spector. It features soaring, heavily echoed vocals, and a sing-along chorus. The children singing in the background were from the Harlem Community Choir and are credited on the song's single.

Directly following John Lennon's death on December 8, 1980, the song was re-released in the UK on December 20 of that year.

Although the song is a protest song about the Vietnam War, it has become a Christmas standard and has appeared on several Christmas records. One of the best known versions was recorded live by Melissa Etheridge. Los Angeles based artist John Romano scored a hit with the song during the 2005 holiday season.

Closely related to the song: in late 1969, John Lennon and his wife Yoko Ono rented billboards and posters in eleven cities around the world that read: "WAR IS OVER! (If You Want It) Happy Christmas from John and Yoko." Five of the eleven cities included in the billboard campaign were New York, Tokyo, Rome, Amsterdam, and London. At the time the United States was deeply entrenched in the Vietnam War, which would later become a major political debacle.

The song is heavily covered in rock circles by bands such as Thrice, An Angle, The Used, and Acceptance.

It was also covered by the finalists of Pop Idol 2 in 2003 and by Rebecca St. James on her album entitled Christmas.

A Swedish language version of the song is known as Låt julen förkunna, and that text was written by Py Bäckman and recorded by Tommy Körberg and Sissel Kyrkjebø in 1989.

The meter of parts of the song is identical, and the tune similar...

A very Merry Christmas
And a Happy New Year
Let's hope it's a good one
Without any fear
...to the verse of a traditional folk tune called Stewball, sung by various artists over the years including Peter, Paul and Mary and Joan Baez:

Old Stewball was a racehorse
And I wish he were mine
He never drank water
He always drank wine
