I remember a Zappa suite with the lyrics, "We gotta send Santa Claus back to the rescue mission, Christmas don't make it no more, You know that murder and destruction scream the toys in every store" or something like that--I also remember, from the Kinks, "Father Christmas, give us your money, we'll beat you up if you make any noise...."
So there is very good news for you, Mick, and that is that there are some very unsentimental christmas songs out there--
