Above: An audience clip of Weir and Lesh’s performance last night

Phil Lesh and Bob Weir performed together last night at a benefit for the New York Historical Society. The intimate event was a fundraiser for a Grateful Dead-focused exhibit at the New York Historical Society that is scheduled to open this March. The evening drew something of a high society crowd that included real estate guru Tony Malkin, the owner of the Empire State Building (the iconic building was lit in honor of the Grateful Dead this past Monday).

Lesh and Weir greeted patrons as they entered the room and later signed autographs and other memorabilia. Both musicians also delivered brief remarks—Lesh drew the evening’s biggest response by introducing Weir as his “best friend.” The New Jersey-based Grateful Dead cover band Wigjam also performed throughout the party and invited out the Grateful Dead members for Bob Dylan’s “When I Paint My Masterpiece” and the hillbilly anthem “Goin’ Down the Road Feeling Bad.” Weir will perform with RatDog at New York’s Beacon Theater this evening.
