Based on the books by P.L. Travers and the 1964 Walt Disney film, Jullian Fellows’ theatrical adaptation of Mary Poppins promises to “transport audiences to the Banks’ household on Cherry Lane as well as the rooftops of London” while revisiting such classic songs as “A Spoonful of Sugar” and “Super-califragilisticexpialidocious.” Jonathan Pennington Studios produces the Cameo’s production.
