Celebrities are typically eager to tell you what they think about nearly any news event — except when it's summer, and they're on vacation, and they've stopped paying attention to the news. We bumped into Sopranos gals Edie Falco and Aida Turturro at the Dave Matthews concert for the Ross School, held in East Hampton Saturday night, and we asked whether Lindsay Lohan would ever work again. "I don’t know what goes on," Falco said. What about you, Aida? "I don’t know what happened," Turturro seconded. "I’m out in Montauk; I don’t even know." Shifting gears, we asked Joan Allen about Eliot Spitzer's recent troubles. "I’ve been gone a lot," she said, begging off. "I was in Greece with my daughter, and I just kind of got back. I’m out of the loop with what’s going on." Billy Joel, who's playing the next Ross concert was at least able to answer a question. What did he have on tap for next week? "For this kind of gig? I’m going to keep it hit heavy," he said. "I don’t think you want to go too obscure for these prices." No, no, you don't: Tickets to the five-show series cost $15,000. —Lillien Nathan
