Sorry, but I can't ID this song specifically.  It definitely sounds like library/production music, similar to stuff found in the "Ren & Stimpy Production Music" or "Music for TV Dinners" collections from years ago.  Another similar collection is the "Golden Age of Light Music" series by Guild Music.  You could also search APM Music's collection.  I think finding this specific song will be like finding a needle in a haystack, but you would certainly would find a lot of other fun music in the process.  By the way, Guild has some fantastic Christmas albums in their Light Music collection.

I thought it could possibly be from a soundtrack, something like Santa Claus The Movie or some such. But maybe not. I definitely don't recognize it.

I've talked about the Guild releases extensively here on the board over the years as my friend Alan Bunting did the remastering for label owner Kaikoo Lalkaka, who I also know and is a terrific guy too. For my exclusive announcement of their third CD release from 2015, click here.
