STAGE TUBE: Winners Announced on NBC's THE SING-OFF Finale

On last night's finale of NBC's singing competition THE SING-OFF, Pentatonix was crowned the winners, beating out runners-up Dartmouth Aires and third place finishers Urban Method. The a cappella group was awarded $200,000 and a Sony recording contract prize. 

The Top 3 groups performed before a live audience last night.  For the first round, the groups lent their voices to a charity of their choice, filming public service announcements for each organization in order to raise awareness.

For the second round, the groups performed with judges Sara Bareilles, Ben Folds and the show's host, Nick Lachey. 

All of the Top 10 groups returned for an exciting performance, with all the females singing Aretha Franklin's 'You Make Me Feel (Like a Natural Woman)', and  the men rocking out to Bruce Springsteen's 'Born To Run'.  Afro-Blue, who were eliminated from the competition last week, also performed with Smokey Robinson with the classic hit, 'You Really Got a Hold On Me'.

For the show's opening number, the Top 3 groups came together for a performance of Michael Jackson's 'The Way You Make Me Feel'.
