20/20: All Access Nashville With Katie Couric 9 p.m., Channel 5

Katie Couric goes country in this special that finds her chatting with some of the stars making noise out of Music City. They range from superstar Taylor Swift (in the midst of the media blitz for her new album “Red”) to current Billboard No. 1 album holder Jason Aldean (who recently announced he would play Fenway Park next summer). She also chats with LeAnn Rimes, who has become a tabloid fixture in recent years and discusses her treatment for anxiety. Also visiting with Couric and correspondents in the special are Reba McEntire, Carrie Underwood, Miranda Lambert, Martina McBride, and Luke Bryan. Pictured: Couric (left) with Swift.
