Pentatonix - God Rest Ye Merry Gentlemen--Sharing Music I Like

Since it's Christmas time, it's time to share some Christmas music, right?

God Rest Ye Merry Gentlemen has always been one of my favorite Christmas songs.  A few years ago, when I was still living in Vietnam, I was searching for an online version of that song to share with my kids, and discovered this version.  Which I like.

I've never heard of this group before, but their Wikipedia page is HERE.
