We were not ready to the celebrate the "Last Song of Summer" Saturday afternoon, (GofG Hamptons is in a current state of denial that September has arrived) but there were plenty of socialites, celebrities, patrons, philanthropists, and Hampton locals who were. The Watermill Center hosted a benefit concert Saturday evening bringing the talents of Rufus Wainwright, Norah Jones, and Martha Wainwright to the stage at the Ross School. More photos below...Guests including Mary Louise Parker, Angelica Huston, Isabella Rossellini, Dalia Oberlander, and many more enjoyed the rainy Saturday indoors as they bid farewell to summer...
