I find it very odd that so many people seem to know this song and yet we have never identified any recordings or any printed sources.

I can't find any mention of it in Google Books, Allmusic.com, ASCAP.com, BMI.com, GraceNote.com, WorldCat.com, or in the catalogs of The National Library of Australia, The British Library, The Library of Congress...

Is it possible we don't even have the correct title yet?

I've been assuming the title is TELEPHONE AND TELL OLD MR. SANTA CLAUS, but I've also tried a few variants such as OLD MR. SANTA CLAUS and OLD MISTER SANTA CLAUS.

Any ideas where the song might be found? Or what the title might be, if it isn't one of the above?
