Though I'm not a Christian, I love singing. Doesn't matter what. One of my favorite kinds of songs is the carol with a descant line. When I was younger, I used to be able to handle the formal, full tenor range; my mother is a soprano. Singing carols in church or while wassailing we used to trade off the descant part while the rest of the singers would keep the melody and harmonies going.

WOW!!

P.S. LOTS of the songs mentioned here I've never heard of. I'll have to dig some of them up. But I will say -- with a bit of a mischievous smile -- I saw several mentioned that are actually rather pagan: e.g. Holly and the Ivy.
