Time to Groove With the Saturday Serenade! [VIDEO]

Here's a classic music video for your Saturday!

We're past Thanksgiving and Black Friday, so it's time to break out the Christmas videos on the Saturday Serenade!

This video is getting all sorts of buzz on social media, and it is very well justified!

The a capella group Pentatonix was formed in 2011 in Arlington, Texas. They rose to prominence in the same year by winning the third season of the NBC-TV show, "The Sing Off."

In 2014, they released their second full-length Christmas album, "That's Christmas To Me', and this song is one of the cuts from the album.

From Pentatonix, this is "Mary, Did You Know."

Enjoy!
