The Southern Oregon Chapter of the Sweet Adelines presents its annual chorus show, "And All That Jazz," featuring mesmerizing vocal harmonies and rousing jazz numbers.

The award-winning group, directed by Martha Segura, will present its barbershop, four-part harmonies at 3 p.m. Saturday, Sept. 18, at the Rogue Valley Christian Church, 1440 S. Oakdale Ave, Medford.

In March 2010, the local chapter, known as the Southern Oregon Sound, placed second at a regional competition in Spokane, Wash. — only one point short of first place.

The program opens with a staged or "fake" pre-show rehearsal, in which the women, dressed in fitness clothing, complain about waking up so early to workout. This first act features lively songs to rally the women's spirits, including "This Joint is Jumpin'," "Red Red Robin" and Irving Berlin's "I Love a Piano."

Following the "workout," the all-male Rogue Valley Harmonizers, directed by Don Meeker, will present a Broadway package, Then the Sound, formally attired, return to the stage to present their own Broadway show. This second act features familiar songs from the stage and screen, including "All That Jazz;" "Everything's Coming Up Roses" from the 1959 Broadway musical "Gypsy;" "Tonight" from the 1957 Broadway production "West Side Story;" and "Somewhere Out There" from the 1986 animated film "An American Tail."

"Each and every chord has its own ring to it," says Patty Crumrine, assistant director of Sound. "What we seek is that barbershop sound that makes every hair on your arm stand up. Every vowel and every note has to be perfect."

The men will rejoin the women for an eight-part finale, singing "I Would Like to Teach the World to Sing."

Throughout the program, the audience will hear scores performed by several other local quartets, including the Martha's Vineyard quartet featuring Segura, Barbara Couch, Summer Cisneros-Couch and Nancy Freeman; the Tone Deaf quartet featuring Michael Biggs, Doug Borngasser, Al Robins and Tom Walker; the Hopscotch quartet featuring Pam Cartmel, Danielle Myers, Susan Reimer and Dianne Tighe; and the Gateway Connection quartet featuring members of the Northern Gateway chorus out of Redding, Calif.

Sweet Adelines International is the world's largest singing organization for women, with 25,000 members worldwide.

Proceeds from the concert benefit the Southern Oregon Sound and help to support vocal music departments at local high schools.

Tickets cost $10, $20 for families and are available at the Grocery Outlet in Medford, at the door or by calling 541-324-0006.
