If you see country music stars buying new athletic shoes this weekend, they're probably getting ready for Vince Gill's celebrity basketball game and concert. Now in its 12th year, the fundraiser takes place Monday (March 22) at Nashville's Belmont University. Chely Wright, Carolyn Dawn Johnson, Chalee Tennison and newcomer Julie Roberts are the latest artists added to the event. Others confirmed include Rascal Flatts, Dierks Bentley, Cledus T. Judd, Rebecca Lynn Howard, Jimmy Wayne, Matthew West, Trini Triggs and Steve Holy. Representing their respective bands will be Lonestar's Dean Sams, Emerson Drive's Brad Mates, Asleep at the Wheel's Ray Benson, Restless Heart's Larry Stewart and Trick Pony's Keith Burns and Ira Dean. Tennessee Titans Keith Bulluck and Frank Wycheck and former teammate Neil O'Donnell will also appear at the event that raises money for music and athletic scholarships at Belmont.
