Consider the impact of "Riverdance." This, of course, is the percussive, feet-flying Irish step-dancing show that has toured the U.S. more or less continually since 1996 and is back in Chicago at the Oriental Theatre this week. Produced by Moya Doherty, with music by Bill Whelan, it had its debut in Dublin in 1995 with no less than Chicago South Sider Michael Flatley front and center -- he who went on to create "Lord of the Dance" and "Celtic Tiger" -- and along the way it has opened the door not only for all things culturally Irish but also for dance-based Broadway shows like "Burn the Floor." It has been called unstoppable, both in the good sense and the bad, but now it apparently is coming to an end. This national outing is billed as the farewell tour.
Why go: Duh! Last chance to see "Riverdance."
Reconsider: You've seen it. And you have the video on VHS.
