Rush & Molloy reports that the Dave Matthews concert on Sept. 10 at Madison Square Garden will have some big star back up. Brad Pitt and Matthews-bud Julia Roberts will come onstage at the Stand Up for a Cure benefit, and 300 9/11 first responders, some struggling with cancer and lung diseases, will be in the audience. Jordan Belkin, director of the lung cancer research charity, said: "We're honored to have these heroes" in the house the night before the anniversary.
