If the concept sounds more than a little familiar, perhaps that’s because it is: An actor in a play plays an actress playing an actor in a play. It’s all utterly Shakespearean, and in David Greenspan’s “She Stoops to Comedy,” it’s also wickedly clever.

Anyone who knows their Elizabethan drama knows that only males were permitted to perform on stage, portraying every part in every play. Here, Greenspan composes a late valentine to the Bard, and in the meanwhile, crafts an extraordinary ode to all things theater.
