The old Traditional song captures it best:
Here we come a wassailing
Among the leaves so green.
And here we come a wand'ring
So fair to be seen.
And God bless you and send you
Hear a lovely, spirited version, for your enjoyment:
And, finally, see a recipe you can make for the great day:
Merry Christmas to All, and to all a Good Night!
(I will be gone a couple days over the holiday, but I will be accumulating stories to tell you.)
