Final Performance (1) - Pentatonix - "Without You" by David Guetta ft Usher - Sing Off - Series 3

Oh..it's a good thing this is finale night and the judging won't matter nor will the final vote since the winner is already decided lol...probably one of their weaker performances of the entire series which is disappointing since i'm sure people would've liked them to kill it in the finale should they win but you can't win them all.
