Once, many a moon ago, I arranged this for 4-piece choir and unleashed it upon my music theory class at UCLA.
I dislike Christmas music with a fairly intense passion, but I do make a few exceptions. When you're not a Christian sometimes this season feels like you're getting punched in the face every day.
That said, I do have a "Radio Free Xmas", that I will unleash upon you tomorrow.
As for the chorale, I got an A. I wish I had recorded her performance.
