Singer Rosanne Cash, with husband John Leventhal joining her on guitar, performed at a fund-raiser benefiting Martha’s Vineyard’s beloved Gay Head Light. The sold-out event at Flatbread raised more than $120,000 for the restoration and relocation of the landmark lighthouse. “Monk” actor (and Vineyard resident) Tony Shalhoub wielded the gavel at an auction that included a week in a Paris flat and a helicopter tour of the island followed by a catered dinner at the historic light. The Save the Gay Head Lighthouse Committee is now halfway to its goal of $3 million, the cost to move the lighthouse away from the edge of the eroding Gay Head cliffs. (The light now stands barely 45 feet from the edge of the cliff.) Revelers included builder Nat Benjamin, Boston Cyberarts honcho George Fifield, island chefs Jamie Hamlin and Annie Foley, fishing captain Buddy Vanderhoop, island bookbinder Mitzi Pratt, Jim Belushi, environmental activist/producer Laurie David, and tech types Allen Carney and Allen Razdow.
