Fortunately I had a great intern who did a lot of the research on Andy's prices, which of course are phenomenal, but getting them straight - you know, he's reached this $100million plateau that only a handful of other artists have reached, which puts him in the company of Cezanne, Klimt, Picasso, and such.

Andy [Warhol] put on his fey kind of act, but he wanted to be number one and he succeeded. But you never know. Fifty years from now he might not be seen as so important, but the way our whole culture has gone, and the way it continues to go, is his way - for better or for worse.

I think his portraits of Jackie, Liz, Marilyn, Mao, Elvis, Lenin - and objects like the soup cans, the dollar signs, the hammer and sickle, it's all about icons. Its all about what people worship in an irreligious or secular world. In terms of Andy's personality and Andy Warhol as a human being who I was very close to, I still feel kind of sorry for him on a personal level. I mean, he was the ultimate example of great success wrapped around inner turmoil and emotional pain.

Well, it wasn't really a decision on my part although you always hope as an author that a book that goes out of print somehow winds up back in print. These days publishers like to put out-of-print books into e-book form, but I really wanted to do an update.

He [Andy warhol] went out every evening to five or six parties with a tape recorder in one pocket and a camera with extra film and batteries in the other pocket, constantly recording and photographing everyone he came across.

Envy is a surefire party killer.

I took photos from 1976 to when I left in 1993, primarily for Interview and a column I had called "Bob Colacello's Out" which Andy had conceived of. I've never taken a picture since, not even with my phone! It just felt too Andy Warhol to keep going around town taking photographs. And I never really thought of doing anything with them after I left the magazine until this great Art Director Sam Shahid about for or five years ago asked where all of the old photos were.
