Real-life GLEE hits center stage on NBC’s “The Sing-Off” starting Monday, December 6th at 8/7c. The premiere episode will be followed by more shows on the 8th, 13th, and 15th. The live finale will be Monday, December 20th.

I have to recommend to everyone out there if you should ever have the chance to see this show live as part of the studio audience in Los Angeles, you should do so. As someone who saw the first episode of the first season live, it just doesn’t compare to watching it on television. If you have a 5.1 surround sound system, that would be the next best thing!
