Barbershop Bonanza showcases its 18th year of sweet harmonies on Sunday, June 5 at 2:00 p.m. at San Juan Community Theatre.

Directed by Angel Michaels, the Bonanza honors this uniquely American music with contemporary and old-time favorites full of four-part harmonies. The Bonanza is hosted by San Juan’s mixed barbershop chorus, Island Chordsmen Plus and features the island’s local women’s a cappella ensemble, Sound Vibrations. And new this year, is the 4 for Fun! Quartet featuring islanders Dick Saylor, Doug Rowan, Paul Arroyo and Angel Michaels

This year’s visiting groups include the An-O-Chords barbershop chorus of Anacortes. Chartered in 1955, the An-O-Chords have earned a national reputation as one of the happiest chapters in the country. One of the quartets from the group, the Boon Brothers, will also highlight the Bonanza.
