Berkshire Bach Society will present its annual Messiah Sing at 4 p.m. Saturday, Nov. 28, at First Congregational Church, 251 Main St.

The Messiah Sing is based on Handel's English language oratorio composed in 1741. The audience becomes the chorus. Bring your own score or borrow one at the door.

Singers are led by Frank Nemhauser, a professional choral director, and are accompanied by the Berkshire Bach Players, a instrumental ensemble of professional musicians.

The event is free; donations are welcome.
