Diana Vreeland was "the Empress," the avatar of the age. An old name or old money were not enough to get you into Studio 54 - or Interview magazine, for that matter. You had to have a lot of something else, like looks or brains or wit or fabulous clothes.

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.

Well that's what Andy wore to bed. You know, the oxford button-down Brooks Brothers shirt that he's been wearing all day and his big long socks. He'd just take off his jeans and his boots and go to bed. Then he'd change into a fresh ensemble after he had breakfast the next morning.

I mean when the book first came out it was not a bestseller, but it got good reviews and at that point I was done writing about Andy, done talking about Andy....but now, I kind of love it. All these smart, attractive young people think I'm cool! So here I am a guy in his sixties with all of these interesting friends in their twenties. It's very stimulating and keeps me very much in the present.

You can't hang around geniuses forever because they end up taking everything you've got. That's why they're the genius and you're not.

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 could write an entirely new book about Andy Warhol, but I don't think I will. I certainly don't think Nancy Reagan would like that, as she's been patiently waiting for Volume 2 of my chronicle of the life of her and Ronnie.
