Last time Joan Jett stopped in town, I was fortunate to land a meet-and-greet with her before the show. I was in awe of the rock icon and feebly stuck my hand out for a shake. She was genuine and reserved, yet she held a badass aura that shined on stage that night. I saw it up close and personal — she invited me and my friends to watch the Kentucky State Fair performance from the stage, her stage. It’s a night I’ll never forget, and my admiration for her has only grown with the recent film “The Runaways,” depicting the rise and fall of her first all-girl group in the late ‘70s. She returns to the fair tonight for a free concert — you’ll hate yourself if you miss it.
