Kenny Chesney sold out his June 23 stadium concert in Philadelphia's Lincoln Financial Field in 15 minutes, equaling the time it took to sell out another stadium concert scheduled near Boston this summer. He will be joined by Brooks & Dunn, Sara Evans, Sugarland and Pat Green for the stadium shows, including other stops in Pittsburgh, Cleveland, Detroit and Seattle. On an additional series of arena dates for his Flip Flop Summer tour, Sugarland and Green will open the shows. His next scheduled concert date is April 12 in Omaha, Neb. Chesney also played two shows at small bars in Key West, Fla., last week and announced the Academy of Country Music nominees on Monday morning (March 5) in Nashville.
