STAGE TUBE: Dartmouth Aires Perform Queen Medley on NBC's THE SING-OFF

On last night's episode of NBC's THE SING-OFF, The Dartmouth Aires gave an impressive performance of three Queen hits. NBC has announced that on next week's episode of the singing competition, the groups will be "Rocking Out and Goin' Country", as each of the remaining six groups performs a rock classic and a country hit to determine who will be leaving the competition.

THE SING OFF is the unique competition series that sings a different tune and is hosted by multi-platinum recording artist Nick Lachey, returns for season three this fall in a weekly format with two-hour episodes.

The show scours the country in search of the best a capella groups, ranging in size and age. This year the competition has expanded to the 16 very best groups who will perform popular songs in a weekly competition that will culminate with a live finale revealing the grand-prize winner. The groups will be competing for America's vote and a chance to walk away with the ultimate prize -- a Sony Music recording contract and a $200,000 cash prize.

There's no lip-synching, back-up bands or safety net. One group will be eliminated each week during this one-of-a-kind battle of voices that will lead up to a live finale -- where viewers will decide the winner.

Celebrity judges who will critique the singing groups, using their musical expertise, are Ben Folds (Ben Folds Five), Shawn Stockman (Boyz II Men) and Sara Bareilles ("Love Song" and "King of Anything").

THE SING OFF airs Mondays at 8/7c on the NBC network.
