A glittering crowd from the worlds of music, business, film, TV and art gathered at the oceanfront East Hampton estate of Larry Gagosian on Saturday to honor the “Man With the Golden Ears,” Clive Davis. Paul McCartney, Jack Nicholson, Jon Bon Jovi, Owen Wilson, Roger Waters, Jimmy Buffett, Anjelica Huston, Chevy Chase and Peter Beard were spotted alongside moguls Lorne Michaels, Jann Wenner, Steve Schwarzman, Sandy Gallin, Roger Birnbaum, Leon Black, Len Blavatnik, Peter Morton and Ron Delsener. Davis arrived about 45 minutes after the party started. Thirty minutes later he was still in the entry foyer as guests greeted the man responsible for the careers of acts ranging from Bruce Springsteen to Alicia Keys.
