'The Sing-Off' preview: Eight new groups perform - video
The third season of the NBC vocal competition is the biggest yet, with 16 groups hoping to impress judges Ben Folds, Shawn Stockman and Sara Bareilles with their a cappella performances.
Watch a preview of tonight's episode of The Sing-Off below:
Last week's season premiere saw the first eight of the 16 groups performing, before the eight siblings of Fannin Family and the slick all-male group Cat's Pajamas became the first two groups to exit the competition.
Fannin Family had performed 'Who Says' by Selena Gomez & The Scene, while Cat's Pajamas had chosen to perform 'Some Kind of Wonderful' by Grand Funk Railroad.
