NBC's "Sing-Off" Returns Tonight

NBC's a cappella singing competition is returning for another holiday season. Hosted once again by singer Nick Lachey, "The Sing-Off" will begin its second season tonight. Also returning for another installment are celebrity judges Shawn Stockman, Ben Folds, and Nicole Scherzinger. This year's season will include one slight change, however, as the number of groups in the competition has been increased from eight to ten. Viewers will get to vote from home for their favorite performances, with the winning group receiving a Sony Music recording contract and 100-thousand-dollars. Tune in to NBC tonight at 8:00 p.m. Eastern for the season premiere of "The Sing-Off."
