When I was in grade school we went to school an hour early as there was carol singing, for the entire month of December. Some of my favourites:

* Little Drummer Boy
* Rudolph the Red-Nosed Reindeer
* Frosty the Snowman
* Silent Night
* We Three Kings

We used to get in trouble if we changed the words!
