Meet Andy Offutt Irwin: Storyteller, humorist, singer, songwriter, musician, whistler and a walking menagerie of sound effects and dialects.

The performer, described as equal parts mischievous schoolboy and the Marx Brothers, peppered with a touch of the Southern balladeer, will perform Saturday, Sept. 15, at the Sautee Nacoochee Center. Show time is 8 p.m.

Irwin’s stories often feature the adventures of his 85-year-old widowed, newly minted physician and aunt, Dr. Marguerite Van Camp.

He will make his fifth appearance this October at the National Storytelling Festival, and he has seven years been a teller in residence at International Storytelling Center. He was a guest artist at La Guardia High School of Art, Music, and Performing Arts in New York and has been a keynote speaker and performer at the Library of Congress-Virburnum Foundation Conference on Family Literacy.

Irwin was the host of SNCA’s long-running radio show, “Evening Star.”

Tickets are $22, $16 for SNCA members, on sale at www.snca.org or by calling the Center box office at 706-878-3300 from 9 a.m. to 5 p.m. Monday through Friday.
