WHAT The classic overnight-sensation musical, "42nd Street," dances its way across the Engeman Theater stage, starring Patrick Ryan Sullivan as producer Julian Marsh and Darien Crago as Peggy Sawyer, the chorus girl who gets her big break. But the backstage star is choreographer Melissa Giattino, who grew up in Bellport, where her mom, Diane, runs Stage Door School of Dance, soon to be taken over by Melissa's sister, Mary. Giattino estimates she'll need at least 20 tickets for her family. "Long Island was a great place to grow up," she says. "I'd go see Broadway shows all the time." As for "42nd Street": "I've played almost all the roles, between the revival and tours." Giattino is reunited with fellow "42nd Street" alum Mark Adam Rampmeyer, who directs the Engeman run. Ultimately, she hopes to bring her own show to Broadway with "Two on Tap" dance partner Ron DeStefano.
