Playbill reports:
Mary Poppins is back, and she has a familiar-looking lamplighter in tow. Lin-Manuel Miranda joins Emily Blunt on the big screen in the upcoming movie musical Mary Poppins Returns, and in a new sneak peek, the Tony and Pulitzer Prize winner performs one of the new songs heard in the film. Miranda, as Jack the lamplighter, leads a high-energy “Trip a Little Light Fantastic” – cockney accent included. The song is part of the score composed by Hairspray and Smash duo Marc Shaiman and Scott Wittman.
