Boomers Rock Tribeca!• RSVP to Help benefit. Tribeca Rooftop, 2 Desbrosses St., nr. Hudson St., 7:30 p.m. The red-hot scheduled-guest list includes Bill Clinton, Al Gore, Joe Torre, Elton John, Lewis Black, and Jon Bon Jovi. We respected JBJ before in a somewhat patronizing way, but since we started doing karaoke more, our respect is complete and sincere. “Livin’ on a Prayer” is tough to sing when you don’t have the rest of the frat party backing you up.
