"I was really nervous," recalls Jackie Madunic. "I love Tina Turner - she's, like, one of my idols - and I was terrified."

Madunic is describing the first time she rehearsed her role as Turner in the Quad City Music Guild's production of Beehive, and the actress' fears are understandable. The revue, running March 23 through 25, is a celebration of the 1960s' most prominent female musicians - among them Turner, Janis Joplin, Lesley Gore, Aretha Franklin, Diana Ross, Connie Francis, and Annette Funicello - yet in addition to portraying one of our country's most identifiable rock icons, another factor is conceivably adding to the performer's nervousness: Madunic is white. (As, it should be noted, is actress Sarah Ulloa, who plays both Franklin and Ross.)
