"The Twelve Days of Christmas" has to be the most monotonous Christmas song ever. I don't mind truncated versions, but the whole enchilada ... definitely not great. I'm listening to Connie Francis' version and she did the whole thing.
As far as Christmas songs that are so overlooked, and it makes you wonder what ever happened to them, the biggest one that comes to mind is the one that says, "There's a song in the air, there's a star in the sky, there's a mother's sweet prayer, and a baby's low cry." What is it about that song, that you can go the whole, entire Christmas season without hearing it once.
It seems like we used to do it for church programs or maybe in school. But it's one that dwells at the edges of existence. I've heard several Christmas songs dozens of times this year but not that one!
