Watch out, Nutcrackers! For 10 years now, the Rockettes have been high-kicking their way to making The Radio City Christmas Spectacular an annual Chicagoland tradition. True, this isn’t the only Rockettes tour hitting major cities, but think of all the money you’re saving by taking a trip to Rosemont instead of seeing the original at New York’s Radio City Music Hall. Write it off as excessive high camp or embrace it all as good old fashioned American razzle-dazzle. The Radio City Christmas Spectacular playsNov. 20-Dec. 7 at 3 p.m. at the Rosemont Theatre, 5400 N. River, Rosemont. Tickets are $25-$65. 312-559-1212. (Also, see the interview on page 22.)
