The Forgotten Jazz Scene

How could the repeal of prohibition in 1933 affect the onset of The Sixties in Ann Arbor? It sounds like Chaos Theory, where the flapping of a butterfly wing in Brazil affects the amount of snow that falls in Greenland. But such an effect did occur. And the sad thing is that the scene I am about to describe is hardly remembered. I keep waiting for someone to write about it, but it might have to be me!
