Christmas Song Trivia Day 6: "Joy to the World!"

In my opinion, this is one of the most jubilant of the Christmas songs, and beautifully conveys the whole message of Christmas. It was actually written to refer to the trimphant second coming of Christ, not his first coming as the Baby of Bethlehem. This video below is a bit lengthy, but it was magnificent and worth the wait. 

Trivia question: What composer wrote the music that is used for this song? See the rules/prizes below. If you want to answer questions from previous days for extra entry points, click here.

Directions/Rules/Prizes:
Here's how it works:
1. Every day or two (or three), I'll post a seasonal song and ask a trivia question about it. 
2. Everyone who comments and answers correctly gets one entry in the giveaway to be held at the end of the contest. Googling answers is entirely acceptable and probably required. You may leave a comment on this post as well. 
3. You may answer any of the questions as long as the contest is going. 
4. You can get an extra entry for tweeting or sharing on Facebook. Just leave that in your comment. One entry for each day you do that. 
5. The contest ends whenever I say it ends. Probably January 31st. But we'll see.
6. At the end of the contest, I will do a drawing. 
7. The winner of the drawing gets to pick their prize from the following list. The runner-up gets to pick their prize from the remaining list. And the second-runner up then picks from the remaining items. And so on. We'll give away as much stuff as we have, so there will be multiple winners. 
Easy, easy, right? Now, the fun part. There are some great prizes. Courtesy of some other authors, we've got a bunch of stuff. I appreciate Rebecca Belliston, Cindy Bennett, and Angie Lofthouse for donating some of their work! And again, the winner gets to choose what they want.
