If you are a Dierks Bentley or Gavin DeGraw fan, you will want to be sure to watch the Super Bowl pre-game show on NBC starting around noon PT. Bentley and Gavin will sing around that time on the show. They are performing outside the stadium as part of the official Super Bowl tailgate party, and part of each performance will be televised live. They aren't the only musicians to keep an eye out for on Sunday. Idina Menzel will perform the national anthem, John Legend will perform “America The Beautiful” and Katy Perry will lead the halftime show.
