On Saturday night and deep into Sunday morning, the Brooklyn Academy of Music was filled with bedraggled, bedreadlocked and bewitched Brooklynites, drunk on bohemia and Bud Lite. They were there to pay homage to perhaps the greatest actress of our day: Lindsay Lohan, a woman who not only embodies that particular craft but is the freckled and flawed mascot of our time. Laurel Ptak and I were there too.
