The Little Prince is a play based on the book of the same name by Antoine de Saint-Exupéry, adapted by Rick Cummins and John Scoullar before 2000.
There are several changes from the book, including the omission of the drunkard (tippler), switchman and merchant characters; the removal of a great deal of the narration from the aviator; significant changes to the rose scenes; and a large change in the order of events.
The longest song in the script has to be the Rose and Prince number, which goes by the title of "What a Beautiful day".
Although the play has an entire orchestra performing, it does not necessarily require one in the background for the full effect.
A nicely-tuned piano and a strong chorus will have the same effect as a full orchestra.
