The play will run May 30-June 22 at the East Village space, The Connelly Theatre, a pocket proscenium stage tucked in a school on East 4th Street between Avenues A and B.

Luker's Broadway credits include The Secret Garden—which first made her reputation as a wholesome female lead with a crystalline soprano—Show Boat, The Sound of Music and The Music Man. She has also lent her voice to many concerts. Her non-musical credits are relatively few, making Can't Let Go a distinct change of pace for the two-time Tony nominee.

Luker and Keen artistic director Carl Forsman share an agent and the actress told Playbill On-Line that's how she came to know about the play.

"I read it and thought it a very funny comedy," she said. "I've been wanting to do a play for a while. I've always wanted to do something broader and something more contemporary."

Describing the plot, she said, "There's a zaniness about the story that attracted me. I play a woman who gets besieged during a three-day period in her office by some of her co-workers. It's a slice of life that's a little bit fantastical, but it has some real, touching moments as well. And sort of a surprise device that Keith Reddin put it. I won't tell you what it is, but it's a device that he's been wanting to use." Also in the cast are Cheyenne Casebier, Glenn Fleshler, Brian Hutchinson and Greg Stuhr. Forsman directs.

The Keen Company has had success in the past attracting name actors to its productions. Its second outing, the New York premiere of Conor McPherson's The Good Thief, starred Brian d'Arcy James.

This is Keen's first production since last fall's revival of Three Cornered Moon.
