Opening Night Party at the Metropolitan Museum

Every year the Costume Institute at the Metropolitan Museum in New York hosts a Gala to celebrate the opening of a new fashion exhibition. It's the Oscars of the West Coast, where a red carpet is unrolled and celebrities walk it with the best fashions of the world. Fashion rules the night.
This year's Gala theme was Superheroes, and the whole blogosphere posted images of their favourite guests with their favourite outfits. We all knew who, what and when but, did we ever wonder what was behind the walls? How was the party? What did the people do inside?...
I found some footage on youtube from a 1982's Opening gala party at the MET, invitee included Andy Warhol, Gianni Versace, Diana Vreeeland, Marisa Berenson, Halston, Bianca Jagger... what a night!
