Greta Oglesby, the singer-actor who put her powerful stamp on the title character of Tony Kushner's "Caroline, or Change" at the Guthrie last year and was honored with an Ivey Award for her dynamic performance, is getting a chance to show her power on a larger stage.

Oglesby has been invited to deliver the show's signature song at New York's Lincoln Center. She will sing "Lot's Wife" in a March 5 concert honoring composer Jeanine Tesori that is part of center's American Songbook series.

"I got a call to do it in late December but didn't know how I could," Oglesby said Monday from Ashland, Ore., where she is playing Queen Gertrude in the Oregon Shakespeare Festival's production of "Hamlet." "I'm on contract here through October and couldn't see a way to New York."

But the festival, led by artistic director Bill Rauch, agreed to let her go. She will use the long flight to bone up on another script, she said, since she is performing in several shows in repertory.

Oglesby's husband, Rev. Dennis Oglesby, is pastor of Park Avenue United Methodist Church in Minneapolis. He is flying to New York to join other family members in support.

"My brother is pretty good with pictures, I hope he gets some good ones," she said. "It's such an honor to be asked and I'm so looking forward to it."
