Seat Filler: NYC Theater Guide for March 2012

Rated P for Parenthood
A game and peppy cast of four — Courtney Balan, Chris Hoch,
 David Josefsberg, and Joanna Young — tackle childrearing in a pandering yet largely resonant series of musical and comic vignettes that recall revues like Motherhood Out Loud and I Love You, You’re Perfect, Now Change. The brisk show’s heavy on cheese and maternal humor, but the men get to stretch in an inspired sketch about gay dads raising three horny straight sons.
Westside Theater, open-ended.

Voca People

If you can survive the space-invading audience participation, there’s much to enjoy in this otherworldly musical for fans of Blue Man Group and Glee’s Dalton Academy Warblers. Serving geisha-faced realness and perfect harmonies in the guise of aliens who must refuel their spaceship with musical energy, these Israeli YouTube sensations please the crowd with a cappella medleys of more than 70 hit songs from Queen to Céline.
New World Stages, open-ended.

Gatz
In Elevator Repair Service’s brilliantly bizarre six-and-a-half hour epic, which has returned after a hit 2010 engagement, a random low-rent office employee (Scott Shepard) starts to read aloud from an old copy of The Great Gatsby, F. Scott Fitzgerald’s arguably homoerotic 1925 novel. Gradually, his motley coworkers inexplicably begin to mirror the novel’s plot until they’re all exhilaratingly embodying the characters in period costume.
Public Theater, through May 6.
