It was a time of uncommon possibility and freedom, when Detroit created wondrous and lasting things. But life can be luminescent when it is most vulnerable.

And all of the big shots of the car industry are there, strutting their stuff. And that year, they're feeling especially good because cars were selling more than ever before.

Originally, John Kennedy was going to come speak, and then Lyndon Johnson. Because it was October of '62, neither made it because of the Cuban missile crisis.

Well, here you had a city that was selling more cars than ever before, that had this wondrous music being created, that was so vital to the labor and civil rights of this country, and yet it was dying and didn't see it, except for some sociologist at Wayne State University who predicted that Detroit was losing population by a half-million by the end of that '60s decade, and that that trend would continue taking away its tax base.

And that John F. Kennedy uttered the first variation of "ask not what your country can do for you" in Detroit on Labor Day in 1960. So Detroit was really central to Democratic politics United States. Every Democratic candidate would start their fall campaigns in Cadillac Square.

So, I mean, there's still vast swaths of the city that are suffering from a lack of jobs and poor housing and poor public schools, but they are building momentum - you know, techies, foodies, artists, musicians, all coming to Detroit. So there is this vibrancy. You see it in the newspapers every day - some story about the new Detroit.

I discovered in writing the biography of Bill Clinton that it is actually easier to write a biography of someone who is dead. Although you can't interview them, you have a fuller perspective on their whole life after they're gone and people are more willing to talk about them.
