Country music icon Toby Keith has sold out his third and final concert in Las Vegas, just moments after tickets went on sale. The sold-out shows will take place on December 10, 11, and 14, coinciding with the National Finals Rodeo. Originally, only two shows were planned, but due to high demand the third show was added. Keith recently received the Country Icon Award and made a comeback on country radio with his song "Don't Let The Old Man In." He has also released a new album called "100% Songwriter."
