By conservative estimate, probably 90 percent of the audience at last night's opening of "Chita Rivera: The Dancer's Life" at the Colonial Theatre came prepared to be wowed, having witnessed the double Tony Award-winner's onstage charisma before. She has given us 55 years, after all, in which to catch her act.
As for the 10 percent of us a few decades behind in picking up the banner? Converts all -- again, by conservative estimate.
Rivera, 74, is that winning. Yes, her moves may not be as technically astounding as no doubt they once were, but she still knows how to razzle-dazzle: it's amazing, the mileage she can get out of a crisp gesture, a snappy attitude. Her high kicks may no longer shoot sky-high -- especially the left leg -- but once she's gotten to know you a bit (and she gives the impression of talking one-on-one with the packed theater), she'll explain that discrepancy, along with the history of the past half-century of Broadway dance.
