Mary Poppins (musical)
Mary Poppins is a musical with music and lyrics by Richard M. Sherman and Robert B. Sherman (the Sherman Brothers) and additional music and lyrics by George Stiles and Anthony Drewe, and a script by Julian Fellowes. The musical is based on the similarly titled Mary Poppins children's books by P. L. Travers and the 1964 Disney film, and is a fusion of various elements from the two, including songs from the film.
Anthony Drewe
George Stiles and Anthony Drewe were commissioned by Cameron Mackintosh and Disney to write additional material augmenting the Sherman Brothers' original Academy Award winning Disney's classic 1964 film song score. The stage musical featured a new book by Downton Abbey writer and Academy Award winner Julian Fellowes.
