What's Your Favourite Xmas Song?

Today, after a slightly precarious walkies, I brought the Christmas tree in from the garage. Don't usually put it up this early but some people put there's up last week!

I always get out the Christmas CDs to play while I decorate, some pop songs & some carols & was wondering what our favourites are?

Mine: "Fairytale of New York" by The Pogues & Kirsty Maccoll
