Take some kite flying, throw in a little bird feeding, add an uber-nanny, a chimney sweep and two precocious kids, and you’ve got the makings for a supercalifragilisticexpialidocious evening when the Albemarle High School Players present Mary Poppins. Based on the popular Disney movie, the musical, directed by Fay E. Cunningham, follows the story of “practically perfect” Mary, who floats in to sort out the complicated relationship between Jane and Michael Banks and their stressed-out parents.
