Las Vegas is currently enjoying a wickedly good time with the five-week run of the Tony-Award winning musical “Wicked” at The Smith Center for the Performing Arts, but it’s about to get a little bit naughtier.

The cast of “Wicked” will host a staged concert performance of Richard O’Brien’s cult classic ode to a sweet transvestite — “The Rocky Horror Show” — at the Tropicana Showroom on Monday, Sept. 24.

“The Wicked Rocky Horror Show” performance  in Vegas is just one of many benefit shows the National Touring Company of Wicked has done throughout the country to support charitable organizations. In Vegas, the performance will benefit Broadway Cares/Equity Fights AIDS and Las Vegas’ Golden Rainbow.

Over the past 7 years on the road, Wicked’s National Touring Company has raised more than $2,000,000 in donations for Broadway Cares/Equity Fights AIDS and local AIDS service organizations all over the country.

“The Wicked Rocky Horror Show” will feature the cast of “Wicked” portraying Dr. Frank-N-Furter, Riff Raff, Magenta, Rocky, Janet and Brad. Performers will include: Nicole Parker (Elphaba); Patti Murin (Glinda); Kim Zimmer (Madame Morrible); Justin Brill, (Boq); as well as members of the ensemble, band and the touring staff. The event will be directed by company member Timothy A. Fitz-Gerald with choreography by Napoleon W. Gladney & Shanna VanDerwerker. Musical direction provided by Andrew Graham.

General admission tickets are $60 to “The Wicked Rocky Horror Show.” VIP tickets, which include priority seating and a 6:30 p.m. pre-show reception with members of the company, are available for $125. Admission to “The Wicked Rocky Horror Show” is for those 16 and older.

Tickets are available online at: www.troplv.com; in person at the Tropicana Showroom Box Office or by calling (702) 739-2222. All proceeds benefit BC/EFA and Golden Rainbow, and donations are tax-deductible.

In addition to the performance, there will be live and silent auctions for items including opportunities to join the company backstage at the The Smith Center and a chance to bid on a walk-on role in “Wicked” where you will join the cast onstage in a performance.
