Jack the lamplighter has some big shoes to fill as Mary Poppin’s newest singing and dancing companion, but he looks more than up to the task of tap dancing with penguins and anything else the adventure demands of him. Mary Poppins understands the vital necessity of play and is happy to spend a day flying kites with her charges. When Mary Poppins’ coat comes off, you know it’s time to get serious about cleaning up the nursery and taking your medicine, with a nice spoonful of sugar, of course. Mary Poppins is a whimsical delight in her finest music hall attire.
