Forty-three years ago today if you were between the ages of, say, 10 and 20 and you were in Wisconsin, and especially if you were a girl, you were only thinking of one thing: tonight’s concert. You’d sent away for tickets the previous spring and were lucky enough to have gotten one. Good thing, too, because reports surfaced about tickets being scalped for as much as $20. Of course, back in the spring a lot of people thought no one would remember who The Beatles were come September. They were wrong. That $4.50 would prove to be about the best money you’d ever spent.
