Pentatonix perform Holiday Medley on The Sing-Off (VIDEO)

By Rickey ·

Pentatonix returned to the show that made them a household name, The Sing-Off, with a holiday medley on Wednesday, December 17, 2014.

They ended the medley with "That's Christmas To Me" which is my current favorite Christmas song.

Go PTX!
