In the musical, “42nd Street,” the basis of the show is the 1932 novel by Bradford Ropes and the 1933 film screenplay. Fast forward 47 years when the musical hit Broadway. Now, add another 39 years and the show is in the capable hands of the directors and cast for Gladstone Theatre in the Park.

The show is at 8:30 p.m. Friday to Sunday, July 5 to 7, at Oak Grove Park’s amphitheater, located at 76th and North Troost Avenue.

Megan Greenlee is serving as director while Cameo Ibsen is choreographer. Lenette Johnson is the music director with Chelsea Rhodes as stage manager and Daniel Trebus serves as costumer. The technical director is Patrick Weaver. Alison Farley Raffle is the pit conductor and Laurie Mayfield is the accompanist.

The musical is a musical-within-a-musical setting. It celebrates Broadway, Time Square and those who make the magic of the musical theater. There’s the steadfast team of Maggie Jones and Bert Barry, cowriters of “Pretty Lady,” the musical that is being staged within “42nd Street.” In Gladstone’s show, Heather Wolesky and Ray Ettinger play these parts.

The director of “Pretty Lady” is Julian Marsh, played by Kevin Jester. He’s attempting to stage a musical to bring in some funds while keeping people working as the Great Depression hits.

Audrey Lena plays Dorothy Brock, a prima donna who may be past her prime. Natalie Rothfusz plays Peggy Sawyer, the aspiring chorus girl whose first big job is the new Broadway show. Gabriel Van Dyne plays the young male lead, Billy Lawlor.

The score is chock-full of Broadway standards, including “You’re Getting To Be A Habit With Me,” “Dames,” “We’re In the Money,” “I Only Have Eyes for You,” “Lullaby of Broadway,” “Shuffle Off to Buffalo” and “42nd Street.”
