If you’re buying a ticket to the current revival tour of Dreamgirls, the splashy 1981 musical about a Supremes-like 1960s R&B trio, you’re waiting for Effie to unleash her lungs on “And I Am Telling You I’m Not Going” at the end of Act One. You know: The big girl gets the boot from both the group and her lover/manager’s bed but she’s staying, she’s sta-ay-aay-ing, and you and you and you—you’re gonna love her. All available advance evidence (i.e. appearances on The Early Show et al) suggests that you should indeed have reason to adore this production’s defiant diva, Moya Angela, who’s got stronger vocal chops than Jennifer Hudson, the American Idol alum whom Hollywood handed an Oscar for the 2006 movie adaptation. (Let’s not bring Jennifer Holliday, Broadway’s original, ineffable Effie, into this. Them’s fightin’ words.) But this production still has Idol thoughts, casting lovely Syesha Mercado, a 2008 finalist from the TV competition, as Deena, Effie’s friend-cum-Diana Ross rival. And a bit of the film sticks around, too, in the form of “Listen,” a song originally written to give Beyoncé her Big Movie Moment, but which here receives new lyrics as an Act Two duet for Effie and Deena. Whatever. It’s candy for the eye and the ear. Argue about the rest in the lobby. STEVE WIECKING
