I have no idea where this strip club was located and when…but I'd bet serious money that if it was in L.A. or New York or anywhere he traveled, Bob Kane went there and told every single dancer who he was.
I also love the fact that someone thought that the "Batusi," which was passé about an hour after it was introduced, was a selling point for men who might not just go because the dancers were naked: "I really had no desire to see nude women but when I heard they were doing the Batusi, how could I resist?"
