One Voice Chorus Hollywood Squares is an audience-interactive cabaret-style show coming to Duke Energy Theatre this Thursday and Friday. Those attending will be chosen at random (shy folks beware!) to be the contestants in a game show with questions centered around the Broadway shows and performers. Those unfamiliar with the theater world might want to skip this one or bravely risk the possibility of guessing wrongly. Silent auction, too. $20. June 30, 7:30 p.m.; July 1, 7:30 p.m. Duke Energy Theatre, 345 N. College St. 704-372-1000. www.blumenthalcenter.org.
