In the UK, where singles are still a thing, bands frequently write and record Christmas songs in the hopes of scoring a seasonal hit. Greg Lake released this one in 1975, and it’s become one of the more popular holiday tunes of the rock era. Lake intended it as a song against the commercialization of Christmas, but some people mistook it as anti-religious. This video of Lake performing the song in St. Bride’s Church in London — along with Jethro Tull leader Ian Anderson on flute — should put that perception to rest.
