Last week, Twisted Sister blew the roof off the Silverton Casino’s Hideaway Theater. Tomorrow night, it’s B-listed tryster Newt Gingrich’s time to shred. The ex-GOP frontman will be invading Sin City to promote his book, Winning the Future, which we’re told combines boilerplate commentary on Islamic terrorists and America’s core values with dozens of blackjack secrets and strategies. If you’re going to the show, don’t even think about getting backstage unless you’re model-quality (bikini models OK) or have pharmacist-grade Tadalafil to share. Also, take it easy on the polyester. Newt’s pyrotechnics have been known to melt pantsuits as far back as the third row. Tickets are $30. Show starts at 8:00 PM sharp.
