Featuring Davis Bates, this program on Aug. 11, at 11 a.m., will include traditional and contemporary folk songs and stories about nature and animals from New England and around the world. Hear how coyotes got their howl, how foam came to be in the ocean, and more, and be prepared to sing, move and clap your hands. The celebration includes a short lesson on how to play music with spoons from a kitchen drawer and a guest appearance by a dancing wooden dog named Bingo.
