Brad Paisley, Trisha Yearwood, Josh Turner and Julie Roberts performed Sunday night (Oct. 5) at Nashville's Ryman Auditorium during a special performance of the Grand Ole Opry. The show was presented to an invitation-only audience that included national media visiting Nashville for Tuesday's (Oct. 7) presidential debate at Belmont University. Paisley, Yearwood, Turner and Roberts are Belmont alumni. Darius Rucker appeared at Sunday's concert, but CBS News chief Washington correspondent Bob Schieffer and his country band, Honky Tonk Confidential, also performed two songs. The debate at Belmont will be moderated by NBC's Tom Brokaw, but Schieffer, host of Face the Nation on CBS, is scheduled to moderate the third presidential debate taking place Oct. 15 at Hofstra University in Hempstead, N.Y. Schieffer told the crowd at the Ryman, "Can I say something I've wanted to say all my life? I'm Bob Schieffer, and I'm proud to be on the Grand Ole Opry! I'm appearing between Trisha Yearwood and Brad Paisley. I want to moderate that third debate, but I'll tell you, I won't be feeling near the pressure I'm feeling tonight." After singing with his band, Schieffer returned to the stage to help Paisley close the show.
