If you love the sounds of very close harmonies sung without any instrumental accompaniment, then The Rogue Valley Chapter of the Barbershop Harmony Society has a surprise for you. The organization will present its annual show at 2 p.m. and 7:30 p.m. Saturday, June 2, at the Craterian Ginger Rogers Theater, 23 S. Central, Medford.

The theme for this year's show is "Harmony on the Air," a musical tribute to the songs and commercials heard on old-time radio and TV. The first half of the show salutes the radio era. The second half of the show recalls the TV era.

On the program are performances by the Rogue Valley Harmonizers, Hi-Fidelity, Just in Time, Southern Oregon Sound, Delusions of Grandeur and A Salute to Kids performed by 40 fourth- and fifth-graders at Orchard Hill Elementary School who have participated in the Get America Singing Again program.

This year's headliner is the barbershop quartet Hi-Fidelity, 2002 Buckeye Invitational Grand Champions, four-time Southern California Division Quartet Champions and reigning Far Western District Quartet Champions (for California, Arizona, Nevada, Hawaii and Southern Utah).

Barbershop quartet singing is an original American musical art form. One of the main supporters of this distinctive style of singing is the Barbershop Harmony Society, founded in 1938 and originally named the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America.

Based in Kenosha, Wisc., it is the world's largest all-male singing organization with more than 30,000 singers in more than 800 chapters in the United States and Canada. Another 4,000 barbershoppers are members of affiliated organizations in Australia, Germany, Great Britain, Ireland, The Netherlands, New Zealand, South Africa and Sweden. The group's mission is to "Keep The Whole World Singing."

Tickets are $16 for adults and $8 for students.
