MMario, I might not know many (or any) of the less well known songs, but if I were to list those classic Christmas songs that I do know, it'd still be a pretty long list to type out in it's entirity 'cos it'd include all the stuff I've heard since a wee 'un: 'Away in a Manger', 'Noel', 'Ding Dong Merrily on High', 'Good King Wenceslass', 'Silent Night' etcetera, etcetera. Forgive if I don't cite 'em all! But I think you get my drift.

Hi Old Roger, that sounds an interesting project! What cultures or nations are you sourcing your non-British Christmas songs from, may I ask?

I'm in Essex BTW, not too far from Colchester if that helps?

As you hail from this part of the UK, although it's rather the opposite of your own far more cosmopolitan brief, I wonder if you happen to know of any Christmas songs that are specific to East-Anglia? Some nice helpful people directed me to the song gatherings of Ralph Vaughn Williams for songs from these counties. But I haven't quite got as far as looking into possible Christmas songs from these parts as yet.
