Doll on a Music Box: "Doll on a Music Box" is a song originally from the 1968 musical film, "Chitty Chitty Bang Bang".  It was subsequently performed in the 2002/2005 stage musical "Chitty Chitty Bang Bang" as well.  It is both a musical and lyrical counterpoint to the more free flowing, legato song, "Truly Scrumptious".  In the song, Truly is disguised as a wind up music box doll, metaphorically and actually on a pedestal.  In the song, Truly sings about herself and her rigid nature, all behind the mask of the "doll" she is portraying.  In the motion picture the part of Truly was played by actress Sally Ann Howes.  In the stage musical version, the part was re-created by 19-year-old London actress, Emma Williams.  In 2005, the Broadway "Truly" was portrayed by actress Erin Dilly, who was nominated for a Tony Award that year for the role.
