Theater review: 'Late: A Cowboy Song' staged with bluesy whimsy

"Late: A Cowboy Song" is an early work by Sarah Ruhl, now well-established through "The Clean House" and "Dead Man's Cell Phone" and a MacArthur "genius" grant as one of the country's top playwrights. It's a loping, poetic little three-character doodle about a man and his wife -- mainly his wife, for the husband's a dud and the woman, lost and lonely, is mysteriously drawn toward a lady cowboy on the outskirts of Pittsburgh.
