Christmas Challenge!

Ok, gang, this is going to sound slightly absurd, but hear me out:

In my junior year of high school, my chorus teacher had the chamber singer group sing an acapella (no piano) song called "Wassail" for the Christmas concert. I realize there are several wassail variations out there, and after some study I have deducted that it was--I think--a version known as the "Gloucestershire Wassail."

That damn song haunts me to this day. I am looking for a nice recording of it. By "nice," I mean something you might hear in a church sung in classical, seven part harmony. And by "church," I mean MY church growing up, with a volunteer but very well-practiced and well-tuned choir.

I am not interested in some guy (or girl) with an acoustic guitar, or, god forbid, the Manheimer Steamroller (?) version. No individual voices, either; the beauty is in the group effort.

Here is what it is NOT:

-it is not "Here we come a wassailing among the leaves so green..."
-it is not, Mom, the Kentucky version on Wassail! Wassail!, although that is a lovely song, too.

It most definitely contains the repeated line: "With the WAAAAAAsail BOOOOOOOOWL we'll drink to thee...." (because that was my favorite, belty, music-swelly part).

Bonus points to the person who finds it & posts it online where we can all download and sing along.

Merry early Xmas, and happy wassailing.
