Tom the Piper’s Son (played by Tommy Sands) and Mary Quite Contrary (the adorable Annette Funicello) are about to marry, but the mean miser (the one and only Ray Bolger) has other plans. It’s all in the 1961 film “Babes in Toyland’’ where the action starts in Mother Goose Village with residents dancing and singing on the eve of the wedding (wearing tights in every color, full skirts, aprons, short pants, vests, and hats). 6 p.m. Free. Boston Public Library, Rabb Lecture Hall, 700 Boylston St., Boston. 617-536-5400. www.bpl.org
