Where are they now?

After the filming (from imdb.com):

Filmmakers David Maysles and Albert Maysles returned to Grey Gardens and filmed Little Edie talking about what happened after the initial filming; some of this footage appears in "The Beales of Grey Gardens." Edith Bouvier Beale passed away two years after Grey Gardens premiered, in February 1977. Lois Wright, who briefly appears in the film's birthday party scene, moved into the house after the film was made and wrote a book, "My Life at Grey Gardens," about her experiences there, including the death of Big Edie. Many fans wonder if Jerry Torre moved into the house, but according to all accounts other than his own, he did not. Little Edie had a cabaret act at Reno Sweeney in New York City, and, true to Big Edie's predictions, lived in the house for two years after her mother died and then sold it (to Ben Bradlee and Sally Quinn of the Washington Post). Following this, she lived in New York City, Montreal, Oakland, and Florida. She passed away in Bal Harbour, Florida, in 2002.

The New Yorker ran a short article last year about finding Jerry driving a taxi in New York.
