Chicago Kids Company, Theatre for Children, and the Wilmette Theatre present Sing Along Mary Poppins, an event for the whole family, joining the 1964 film starring Julie Andrews and Dick Van Dyke with a live cast of actors from Chicago Kids Company, for three Sundays this summer. Songs include “A Spoonful Of Sugar,” “Chim Chim Cher-ee,” “Step In Time,” “Let’s Go Fly A Kite” and, of course, “Supercalifragilisticexpialidocious.” This co-presentation continues the two organizations’ commitment to family programming on Chicago’s North Shore.
