The mood was lightened during Harvey Weinstein and Anna Wintour‘s fund-raiser for President Obama when Jimmy Fallon serenaded the crowd with a comedic musical performance on his guitar. A guest reported that Fallon had the crowd, including Obama, in stitches. Guests — who forked over more than $70,000 for a pair of tickets, which helped raise $2 million for Obama — included Gwyneth Paltrow and husband Chris Martin, Alicia Keys, Vera Wang, Gov. Andrew Cuomo, Pharrell Williams, Tory Burch, Lyor Cohen, Aerin Lauder, Kenneth Cole, Bryan Lourd, Gayle King, UBS’s Aryeh Bourkoff, Bob Weinstein and Georgina Chapman. Once Obama, who complimented them as a “pretty good-looking crowd,” left the event at Harvey’s West Village townhouse, the after-party continued down the street at The Waverly Inn for several more hours.
