"Meet Me in St. Louis" is the right movie, Morticia. I actually liked the Halloween sequence in that best.

A song I like but haven't heard much lately is "Thirty-two Feet and Eight Little Tails", but I like all sorts of Christmas music.

Favorites include:

A-Soalin'
Christmas Island (especially the Jimmy Buffet version)
Some Children See Him (well, I guess that one's kind of religious, but it's rare.)
I'll Be Home for Christmas (My uncle, on leave from WWII one year and having to go back, wore my mom's copy of the record out by letting it play over and over and over. I can't hear it without seeing him in my mind.)
Ho Ho Ho and a Bottle of Rhum (Jimmy Buffet again...)
Must Be Santa
Nutrocker
Silver and Gold
The entire soundtrack to "The Nightmare Before Christmas"
and, when I can't take it any more
RuPaul's version of "All I Want for Christmas"

Now I'm going to wander off and see if there's a "favorite Christmas songs, religious thread...
