With the greatest respect RosieH and I do of course regard you as a queen of your sex and everything, but uppus buttus cum coconutus if that's the greatest Christmas song ever. The greatest Christmas song is A Fairytale Of New York by The Pogues, it is so because it can be heard at any time of year and still be enjoyed for the fine song it is, but heard in December it becomes 'of the season'. Bleak, hopeful, argumentative, joyful, optimistic and with a tune that you lends itself to dancing a woman around the floor and sending her skirts a-skirling. With added NYPD choir. What more could a person want from a Christmas song?
