The Friendship Singers of Delmar will present a free Christmas 2018 public concert at the New Scotland Presbyterian Church at 2010 New Scotland Avenue in Slingerlands on Wednesday, Dec. 19, at 7 pm. There’ll be something for everyone—from old favorites (some in surprising form!) and sing-alongs to the haunting strains of Robert Frost’s “Stopping By Woods,” set to music.  Our director is Marie Liddle, accompanist Peg Dorgan, and percussionist Jeff Marshall.
