Westport artistic director Mark Lamos directs the comedy about a gay couple whose idyllic life in Sag Harbor is interrupted when family comes to visit. It runs through Sept. 15.

Beguelin is a Tony nominee for authoring book and lyrics to The Wedding Singer. He also penned the lyrics to the Broadway musical Elf, as well as the book for a new stage adaptation of Disney's Aladdin.

Joining Steggert (Ragtime, The Nightingale, The Grand Manner) and Stewart (The People in the Picture, "Guiding Light") are Kate Nowlin (Anthony and Cleopatra) and Alexis Molnar ("The Next Big Thing").

According to Westport, "Harbor opens with Ted and Kevin, who have been together for 10 years, in their picture perfect house in Sag Harbor. When Kevin's ne'er-do-well sister Donna, whom he hasn't seen in years, and her 15-year-old daughter arrive out of the blue, the pair's idyllic life changes and tensions quickly bubble to the surface. The bonds between kith and kin are tested in this alternately biting, touching and hilarious new comedy about the constantly shifting nature of the meaning of family."

The design team includes Andrew Jackness (scenic design), Candice Donnelly (costume design), Japhy Weideman (lighting design) and John Gromada (sound design).
