Twenty years ago the Grand Olympics Chorus was chartered as a chapter of Sweet Adelines International, an educational nonprofit organization composed of more than 24,000 women singing barbershop harmony.

As part of its mission to provide quality barbershop entertainment for the community, its annual show “Broadway Nights” will feature well-loved Broadway show tunes.

There is one show only at the Sequim High Auditorium at 4 p.m. Saturday, Sept. 26.

Mike Menefee directs both the Grand Olympics Chorus and the award-winning Kitsap Chordsmen who, together with several guest quartets, will be featured performers.

Tickets are $15 and can be purchased at Port Book and News, 104 E. First St. in Port Angeles or Karol’s Accessories, 609 W. Washington St. in Sequim. For more information, visit www.grandolympicschorus.org.

Enjoy harmony, fun, friendship and more while learning barbershop harmony at the group’s open house at 6:30 p.m. Monday, Oct. 5, at 990 E. Washington St. Ste. E103 in Sequim.

Barbershop harmony is produced by four vocal parts singing a cappella (without accompaniment) blending beautiful and exciting chords and harmonies that “ring in the rafters.” Barbershop is wholly an American art form traditionally sung informally by men, “tagging” spontaneously in quartets or small groups.

Barbershop singing has evolved into a sophisticated art form, now performed by fabulous men’s and women’s quartets and full choruses, performing on stage in full costume and with choreography for large, appreciative audiences.
