Of all the people you might least expect to come up with a classic Christmas song, John Lennon is probably pretty high up in the list. Like Jona Lewie’s song from a couple of days ago, this was ostensibly a protest song – in this case, about the Vietnam war – but it’s taken on a life of its own as a seasonal standard. In 1980, re-released after Lennon’s murder earlier in the year, it was famously beaten to the Christmas Number One spot by St Winifred’s School Choir.

The original release of the song didn’t come with a video, what with it being the 70s and all that. So here’s an entirely unofficial version from YouTube. This is John and Yoko and the Plastic Ono Band (to give them their full title), with Happy Xmas (War Is Over).
