You know it’s a big game when the opening act is The Rolling Stones. The Chicago Blackhawks are set to host the Detroit Red Wings in Game 7 of their second-round playoff series tonight ( 5, NBC Sports), one night after the great rock ‘n’ roll band plays the United Center. Taking down the stage after the performance and preparing the ice for the game will be a massive undertaking, but the Blackhawks say they aren’t worried about the surface. They’re just excited about the opportunity after being down 3-1 at one point in the series. Chicago earned a 4-1 victory in Game 5 and captured Game 6 4-3 in Detroit on Monday night. – Associated Press
