According to the Olympia Youth Chorus website, the organization's mission is to, "nurture the appreciation of choral art and the shared experience of creating fine choral music for young singers in South Puget Sound." The Youth Chorus does this, at least in part, with help from presentations like Saturday's Everlasting Melodies, which according to billing will feature tunes familiar to fans of classical and also contemporary, ranging from "The Witches' Chorus" from MacBeth to the Beatles' "Hey Jude." The Olympia Youth Chorus will be joined by Western Washington University's Undefined, an a capella that will only add to the awesomeness.
