I went to Berkeley where Kurt was lecturing at a music seminar. It turned out to be a festival with, among other people, the Mommas and the Poppas, and Country Joe and the Fish. I found myself in an amazing new world I hadn't dreamed of.
I eventually went down to LA and to the opening of a nightclub owned by Nancy Sinatra. Country Joe McDonald dedicated a song to me because we had been hanging out a lot.
He said: "What is your bag, man?"
I said: "I'm an art historian."
He said: "That's a shit of a way to change the world."
Then I went by bus to Chicago, which was just beginning to be the great public art city it has become. There was a massive argument going on about putting up a major sculpture of Babe Ruth or a Picasso. The proponent of the Picasso was a developer and by accident I hung out with him and saw this argument from the right side. I realised art could be engaging.
I eventually left and got a bus to Detroit. As we drove in, the whole of Twelfth St was on fire.
There were jeeps everywhere and the bus depot was full of black refugees. I had come from weeks of privilege in Chicago, staying in a brilliant house with wealth everywhere, and suddenly there was this horror show.
That comment of Joe's stuck in my mind. It seemed to me that art and culture could change the world. He was doing it with his great anti-Vietnam anthems.
A few months later, I woke up in the middle of the night in New York and decided I'd go home, even though I'd been offered a job at the Museum of Modern Art. I was going to engage and prove Joe wrong.
