My all-time favorite (if I can even talk about favorites
of Christmas music) is the The Swingle Singers Christmas
album. It's a perennial favorite and is always in print,
but maybe not at the Best Buy... more likely Barnes and Noble
or Media Play.

My personal (maybe all-time) favorite though was originally
from the movie Holiday Inn. It's sung by Bing Crosby and
the title is "Count Your Blessings" done in the Thanksgiving
segment of the film. But wait, there's more. The version
I think that is the best is done by a piano trio led by Tashiko
Akiyoshi. It is an up tempo "Count Your Blessings" rendered
in the style of Eddy Duchin.

Tashiko Akyoshi and Lou Tabakin have a big band as well.

That title from Anonymous Four from above sounds interesting
to me. Wisht I had access to it.
