Gordon Greenberg (Jacques Brel..., Pirates of Penzance) directs the presentation to play Feb. 19 at The Zipper Theatre at 8 PM. Steve Marzullo serves as the music director. The Zipper Theatre, Ryan Hill and John Johnson present the newly adapted concert version of the 1978 musical based on the Studs Terkel book about the multi-faceted American work force.

Testa — a Tony Award nominee for 42nd Street and On the Town seen recently in Regrets Only and See What I Wanna See — joins Chase (Aida, High Fidelity) and Keenan-Bolger (Les Misérables, The 25th Annual Putnam County Spelling Bee) in the six-member cast that also includes Merle Dandridge (Tarzan), Ed Dixon (Les Misérables) and Roderick Hill (Butley).

Stephen Schwartz (Wicked) adapted the book from the Terkel non-fiction work. The musical features songs by Schwartz, Craig Carnelia, Micki Grant, Mary Rodgers, Susan Birkenhead and James Taylor. The new concert version is adapted from the original by Greenberg.

The director will offer a Brechtian-style take on the musical. "I've always been a great fan of this show and wondered how we might expose the workings of the show itself — by featuring things like stage manager calls and the backstage crew doing their jobs — and by watching fewer actors play more characters," stated Greenberg. "Ultimately though, it's amazingly authentic and human."

The design team for Working will feature Jeff Croiter and Jeff Carnevale (lighting) and Peter Fitzgerald (sound).
