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.
A Saint She Ain't
The music for "A Saint She Ain't" was composed by Denis King, arranged by both King and Chris Walker, lyricized by Dick Vosburgh, and performed by King and Walker on two pianos for the original production. Denis King is a musical composer mostly known for his score of The 1977 Royal Shakespeare Theatre's production of "Privates on Parade", which won the Ivor Novello award for Best Musical. King's score of "A Saint She Ain't" has been criticized by Markland Taylor as, "a matter of hurtling from the sublime to the ridiculous," and compared to his music for Peter Nichols' wonderful "Privates on Parade." Despite criticism of the music of "A Saint She Ain't", Denis King described the experience as, "Possibly the most fun I've ever had writing a musical." 
The music was written for only two pianos, and it is a pastiche of style ranging from jazzy swing to movie musical. From the Evening Standard, Nicholas de Jongh said, "In borrowing from Moliere, "A Saint She Ain't" becomes a triumph of tongue and cheek." The lyrics are full of puns and malapropisms, such as "Time, like Alan Ladd, is short" and "hum a ditty" for humidity, which lend to the endearing but silly qualities and also negative critiques of this Hollywood spoof. One of the songs, "The Banana For My Pie," is considered the show's most memorable song for its "non-stop, sexual doublespeak designed to outrage the Hays Office (Motion Picture Production Code)." The actual vocal aspect of the musical has widely been considered a bit disappointing overall because the actors and actresses were primarily chosen for their comedic talent as opposed to their vocal ability.
