Does Ron Cohen's book tell much about the Chicago folk scene?

Clay Eals' new bio "Steve Goodman--Facing the Music," mentions a good portion of it in it's nearly 800 pages.

I think I know Ron Cohen. There was a folk club in Northern Indiana back awhile that hired me once or twice. And I seem to recall that he was the head man there ??!! I'd appreciate it if someone with his book could check into that.
