All people capable of reading and performing vocal parts are invited to join this venerable local seasonal tradition, a friendly, informal, unrehearsed performance of Handel’s beloved oratorio, directed by Richard Ingram. Over 100 singers usually participate, including professionals, semiprofessionals, serious amateurs, families, and church choirs. A volunteer orchestra of 40 to 50 instrumentalists is also needed; prospective players should email the address below as soon as possible to ensure section balance. Directed by Richard Ingram. Scores provided, or participants may bring their own. (The Prout edition, published by Schirmer, is used.) Orchestra players should bring their own stands. Drinks provided; bring goodies to share. 1:30–4:30 p.m., St. Clare Episcopal Church, 2309 Packard. $5 suggested donation to help defray the cost of using the building. [email protected].
