David Greenspan's GO BACK TO WHERE YOU ARE was completely delightful love note to the theater. The sheer fact that Greenspan was able to pack so much intelligence, humor and time-trippy fun into sixty minutes is a feat unto itself. The ensemble, including Greenspan, was sublime and I was lucky enough to catch the wonderful Mary Shultz in the show before she had to depart early for personal reasons. And as complex as the play was, director Leigh Silverman did a terrific job making everything flow beautifully. Thanks to Playwrights Horizons for their dedication to David Greenspan.
