The public is invited to join area singers in an hour-long free sing-a-long of Handel’s Messiah at 3 p.m. Sunday.

The Part I of Messiah, sometimes called the “Christmas” portion and frequently performed during Advent in concert, sing-along will conclude with “Hallelujah” (chorus) from Part II as the finale.

The Messiah, composed in 1791, by George Frideric Handel was a German, later British, Baroque composer who spent the bulk of his career in London, becoming well known for his operas, oratorios, anthems, concerti grossi and organ concertos.

“We are in hopes there will be a great turnout of participants,” said Brenda Fincher.

To participate in the sing-along, meet in the sanctuary of Trinity Episcopal Church, located at 515 Yancey Street just behind the South Boston Post Office, with overflow parking available at the Main Street United Methodist Church.

The musical manuscript will be available, but bring a copy if one is available. Dr. Tim Duncan will be the organist.
