NBC has announced Clash of the Choirs, a new reality competition series that will aim to find the country's best amateur choir, will air live over the course of four consecutive nights beginning with a special two-hour premiere on Monday, December 17 at 9PM ET.

"This is a wonderful feel-good event series that will get everyone in the holiday spirit and singing along with their TV sets," said Craig Plestis, NBC's executive vice president of alternative programming, development and specials.  "The live format and wide range of music, celebrity and community involvement will undoubtedly create chart-topping drama and enthusiasm."

Clash of the Choirs will begin with several celebrities traveling back to their hometowns to assemble an amateur singing group consisting of everyday people.  The hometown choirs will then compete against one another in-front of a live studio and home-viewing audience, tackling a variety of musical genres that range from holiday classics to current hits. 

Home viewers will be able to vote via phone, text messaging or the Internet to determine which choir wins the competition.  The winning choir -- as well as the celebrity that organized them as a group -- will receive the opportunity to select a prize that will help their hometown, with choices ranging from a new school gym or auditorium to a new neighborhood park.

Clash of the Choirs -- the format of which is based on a series acquired from Scandinavian-based Friday TV -- is being produced in the States by BBC Worldwide Productions, the same company behind ABC's Dancing with the Stars.

"We're thrilled to be back in business with NBC," said Paul Telegdy, BBC Worldwide Americas' executive vice president of content and production.  "It's a really strong relationship and one we hope will continue to bear fruit.  We think Clash of the Choirs is a fantastic idea and perfect for the holiday season."

After its two-hour premiere on December 17, NBC will air a one-hour episode of Clash of the Choirs on Tuesday, December 18 at 9PM ET followed by another two-hour episode on Wednesday, December 19 at 9PM ET.  The show's one-hour finale is scheduled to air Thursday, December 20 at 8PM ET.
