A source close to the situation explained:
Get ready to laugh, smile, and possibly cry in ferosh wiggy terror while watching the (above) AH-Mazing Disney medley!
3/5 of the acapella super group Pentatonix (Kirstin Maldonado, Scott Hoying, and Mitch Grassi) totes wigged out for this mega-group mashup of the best songs from Walt's newest flick, Frozen!
It starts with a silly snowman, transitions to a lonely lady, and finishes with the trio letting go HARD!
You need to ch-ch-check out this HIGHlarious musical moment in time, RIGHT NOW!
