The Medway Public Library will host a children’s program Wednesday at 6:30 p.m. in its Cole Room. “Imagine That,” led by Davis Bates and Roger Tincknell, will be a family evening of hand-clapping, foot-stomping celebration of songs and stories. Free tickets are available at the library’s circulation desk. The program is supported in part by a grant from the town’s Cultural Council. For more information, call the library at 508-533-3217.
