How did I miss this?

Wonderful.   Your joy in music is infectious- thank you!

(hmm...it's now Jan 14...guess it's time to take down my Christmas decorations...)  

I'm guessing you are referring to the tradition of house parties & music between Dec 25th and Old Christmas, yes? Sadly, I only know it second hand, though. If you have any personal stories to share, I'd love to hear 'em.

I've played "Breaking Up Christmas" -- same idea, different name -- for years. In fact, I may get a vid up soon if I have the time. 

That was some nice ol' time dulcimer playing, Mark.  Are you familiar with the old Appalachian tradition called "quitting Christmas?"
