With lyrics based on John Lennon and Yoko Ono’s 1969 billboard campaign which displayed the words "WAR IS OVER! (If You Want It) Happy Christmas from John and Yoko" in cities deeply entrenched in the Vietnam War, it’s perhaps surprising that the song’s original release failed to chart in the US.
Fact: The song’s whispered beginning is a greeting to the couple’s children - Yoko says “Happy Christmas, Kyoko" and John says “Happy Christmas, Julian” - not, contrary to popular belief (and incorrectly included in the lyric sheet from 1982’s The John Lennon Collection!), “Happy Christmas, Yoko. Happy Christmas, John”.
