Last weekend, crowds flocked to the Hamptons for a weekend of concerts at the Surf Lodge in Montauk, an annual fundraiser with the Hetrick-Martin Institute, and much more. From a free concert by Willie Nelson (with a surprise appearance by Jimmy Buffett!), to champagne brunch at Delmonico's, Hamptonites enjoyed all that this weekend had to offer. Check out our round up of the best events from last weekend.
