The production, which had been scheduled to close Sept. 30, will now run through at least Nov. 25.
With direction by Maltby, associate direction and choreography by Kurt Stamm and music direction by Andrew Gerle, the cast currently features Jacquelyn Piro Donovan, Anika Larsen, George Dvorsky and Sal Viviano.
The production at The York Theatre at Saint Peter's is described as "an intimate musical about love, friendship, security, happiness — and holding onto those essentials in a world that pulls us in a hundred directions at once."
The creative team includes James Morgan (sets), Nicole Wee (costumes) and Kirk Bookman (lights). The production stage manager is Bernita Robinson.
