You know “Rigoletto.” But you might not know you know it. If you’ve ever watched “The Simpsons” or “Seinfeld,” if you’ve ever caught a Doritos Super Bowl ad, if you’ve ever played the “Grand Theft Auto” video game, chances are you’ve heard Giuseppe Verdi’s jaunty, insanely catchy “La donna e mobile.”

But it’s far from “Rigoletto’s” only memorable melody, as Opera Las Vegas demonstrates with this weekend’s production at UNLV’s Judy Bayley Theatre. (The performers will sing in Italian, with English supertitles providing a real-time translation.)
