The major treat is a delightful performance by Maureen Anderman as Cornelia Cunningham, a rich woman who is planning to move to a retirement home and giving away the furnishings and other contents of her Upper East Side New York brownstone, designed for the stage with elegant perfection by Michael Yeargan. Cornelia has also willed most of her fortune to various charities, including an organization dedicated to helping children and what she considers other worthy causes, such as Amnesty International.

Gurney has endowed Cornelia with a philosophy that having wealth is improper, given all those who struggle economically in the world, and that money breeds corruption and all kinds of problems. She is outspoken in her beliefs and of very sound mind. Although the serious point is made, the play proceeds in a lightweight manner with entertaining results.

The arrival of lawyer Harvey Abel, amusingly played by Joe Paulik, presents a monkey wrench into Cornelia’s will plans. She doesn’t want to deal with problems, and he is aghast at her indifference. Abel has to fight for her serious attention. He informs her that a young man from Buffalo claims that he is her grandson (she has two grandchildren) as a result of a secret affair her late daughter had with his late father and wants a piece of the coming inheritance to further his own desire of acquiring success and wealth.

Introducing himself as Walker “Scott” Williams, performed with flair and over-the-top charm by Gabriel Brown, he is an African-American, who says that his African-American father raised him together with his understanding wife rather than Cornelia’s daughter going through with an abortion when she became pregnant.

Abel spots him as a phony and con artist, but whatever the savvy Cornelia may think, she takes to Walker, who opens a window of pleasure into her life. All this happens very quickly and improbably, but also enjoyably, thanks to Gurney’s wit and the acting. Pamela Dunlap is colorful as Cornelia’s long-time housekeeper and cook, and Kahyun Kim is pleasing as Jessica Worth, a Julliard student looking over Cornelia’s player piano, containing a trove of Cole Porter songs, as a possible gift to Julliard. She also attracts the romantic eye of Walker.

What happens? Suffice it to say that DNA testing will not be necessary.
