Continuing its 36-year tradition, the Claremont Symphony Orchestra invites everyone to participate in its annual “Messiah” Sing-along, 1:30 p.m. and 4 p.m. Sunday, Dec. 23, at Bridges Hall of Music on the Pomona College campus in Claremont.

Audience members choose whether to sit in the soprano, alto, tenor, or baritone sections, where they will join in to sing all of the choruses.

The orchestra will offer Part I of Handel’s beloved oratorio at both times. Music Director Robert Sage advises, “It’s a good idea to arrive early, since we have had full houses for these programs in recent years.”

The concert is free and no tickets are needed. Attendees may rent the lyrics for $5, purchase them for $10, or bring their own. More information is available at www.ClaremontSO.org.
