What Christmas/holiday songs need to be written?

I’m working on a musical for production this coming December. I have a rough outline including [placeholder] songs. I wondered if any of my fellow jellies have a song that they think needs to be written.

My placeholder range from “There Was Snow on the Ground” to “The Thing About Santa” to “We’re Going to Have a Nice Christmas If It Kills Us”. So any tone is okay with me. I’m serious about the project, but I don’t require you to be.
