Ok need some help with naming a Latin song about Christ's birth before my head explodes.  The song is named something similar to godete (when they sing it they pronounce it go-dee-tee.  Less than a year ago someone here posted the song being lip synched to by some goth chick in a nun outfit but I can't find it.  Her version was from some rock band that changed the lyrics into sex terms (classy).  I heard a section of the real song again today and can't get it out of my head.  I love that song but can't seem to find the name anywhere, usually my search foo is strong but not today.

Sound familiar to anyone?

Gaudete! gaudete!
Christus est natus ex Maria virgine,
gaudete!

1. Tempus adest gratiae, hoe quod optabamus;
carmina laetitiae devote reddamus.

2. Deus homo factus est, natura mirante;
mundus renovatus est a Christo regnante.

3. Ezecaelis orta clausa per transistur;
unde lux est orta, salus invenitur.

4. Ergo nostra contio psallat iam in lustro;
Benedicat Domino; salus regi nostro.

You sir are my hero! I could not get anything close to pull up, I guess I didnt have anything close to that spelling that would flag it.

And here it is sung by one of my favorite groups:
