Funny how non-specific they are about the location. No mention of time, and "Dancing Nightly-Except Monday" is such an odd way to word things.Appears to be late 1940s. I googled around- Don Pablo played Ann Arbor too. Maybe he was Michigan based?
Thanks for commenting. You might enjoy my book about Flint called "Teardown: Memoir of a Vanishing City," a Michigan Notable Book for 2014 and a finalist for the 33rd Annual Northern California Book Award for Creative NonFiction. Filmmaker Michael Moore described Teardown as "a brilliant chronicle of the Mad Maxization of a once-great American city." More information about Teardown is available at www.teardownbook.com.
