Part concert and part show, the program includes sacred and secular music as well as classics, spirituals, popular and country music. There will be costumed musical drama and dance. Performers will play piano, keyboards, horns, flutes and percussion.

Founded in Sunnyvale in 1968 by Leon and Marian Gay, the 35-member chorale is made up of all ages and professions and is well known in the Bay Area and beyond.

The group performs some 24 concerts a year, touring Northern and Central California. They say their purpose is to provide good choral music—well-prepared and colorfully presented—free to audiences who might not otherwise be able to attend such a concert.

The chorale is primarily self-supporting. Each singer contributes at least $200 a year. The directors serve without salary.
