The annual Christmas Service of Lessons and Carols at Williams College will be held at 4 p.m. Saturday and Sunday, Dec. 12 and 13, in Thompson Memorial Chapel.

The identical services feature choral music by the Williams Concert and Chamber Choirs, congregational singing of carols, and the traditional reading of the biblical Christmas story.

There is no admission charge, but all are encouraged to bring an item of non-perishable canned or packaged food for local emergency food pantries.

In addition, a free-will offering will be collected at the conclusion of the service, to the benefit humanitarian efforts initiated or supported by Williams students.

Organist Edwin Lawrence will be joined by several organ students in playing the prelude, which begins at 3:40 p.m.

The Rev. Rick Spalding, chaplain to the College, will deliver a meditation titled "Power to Become," and the Rev. Gary Caster, Catholic chaplain, will serve at liturgist.

Parking is available in the lot behind Thompson Memorial Chapel, on Hopkins Hall Drive.
