When I was a kid I loved Snoopys Xmas, it built the anticipation, It also had the red baron which was technically war and killing so as a little boy I loved it, but now I work in retail and it is played every hour of every day, so sod it Snoopy I hope your Sopwith Camel bites the dust
Probably my two favourites
Slades Merry Xmas EveryBody
Wizzards I wish it could be Xmas everyday
