What is the saddest, or most depressing Christmas/holiday song?

[J.D. Lombardi]

I'm working on a piece for my site (the one in my signature) and I'm looking for as much help possible, but damn, why not carry a conversation on at the same time, right?

I'm looking for what people think would be the most depressing or sad Christmas song they've ever heard.

Personally, I've never heard "Christmas Shoes" but on my facebook page a ton of people are listing that one so I'll have to check it out.

I was thinking something like "Momma Liked The Roses" from Elvis...but I've got to really sit and think about it and go through my own collection of music.

Anyone have any contributions? Hit me with a holiday downer, it'd be most appreciated!
