On that note: JHU's Adoremus performs 'O Holy Night'

Here's one you might have heard before—like, say, yesterday.

For the second consecutive day, we bring you an a cappella rendition of "O Holy Night" (though this time it's not the 'N Sync arrangement).

This version was performed by Adoremus, the Johns Hopkins Christian a cappella group founded in 1995, at the 2012 winter concert. The sound is a little uneven and on the quiet side here, but your patience is rewarded with soaring bursts of harmony.
