Talk about tradition. For the seventh year running, the Laemmle theater chain will present its annual Christmas Eve "Fiddler on the Roof" sing-along, so successful that it's now a fixture at no less than six theaters. Director Norman Jewison turned the hit Broadway musical, based on the classic Tevye stories by preeminent Yiddish writer Sholem Aleichem, into an Oscar-winning film (for Oswald Morris' cinematography and John Williams' score, among others). The Laemmles provide lyric sheets for the Jerry Bock and Sheldon Harnick songs so you can sing along with the irrepressible Topol and the irreplaceable Molly Picon on classics like "Sunrise, Sunset" and "Matchmaker, Matchmaker," not to mention the always-appropriate "If I Were a Rich Man." The film shows at 7:30 p.m. Wednesday at the Royal, West Los Angeles; Music Hall 3, Beverly Hills; Town Center 5, Encino; NoHo 7, North Hollywood; Playhouse 7, Pasadena; and Claremont 5, Claremont. L'chaim, to life.
