Why doesn’t the creamy-voiced crooner have a permanent gig in Vegas? That’s the question that wouldn’t go away while Richard Cheese dolled out his signature shtick—singing lounge versions of popular songs—in the very same place that Steel Panther, his hair-metal counterparts, perform Saturday nights. The cheese-meister displayed all the makings of a Vegas star. He pleased the Old Vegas nostalgists with his swingin’ rhythms, tuxedo jacket changes and prop martini glass. He bagged the boisterous Gen-Xers with lounge renditions of such time-honored classics as “Brass Monkey” by the Beastie Boys and “Ice Ice Baby” by Vanilla Ice. Younger fans would recognize Ke$ha’s “Tic Tok” and a better-than-original rendition of the “Friday” song by the hilariously deplorable Rebecca Black. Señor Queso coated the audience members who might have fallen through the cracks with bawdy humor and a constant effort to move all the pretty girls to the front of the audience. But he really shined when he performed a song all his own, “Christmas in Las Vegas.” So why no residency? Perhaps it’s just too soon. According to his website, the legend of lactose will stop touring after 2012. And maybe, just maybe, he’ll end his travels in Nevada.
