"Scarecrow" is a song on Pink Floyd's debut album The Piper at the Gates of Dawn (1967), though it first appeared as the B-side of their second single "See Emily Play" (as "Scarecrow") two months before. It was written by original frontman Syd Barrett and recorded in March 1967.
The Scarecrow is a play by Percy Mac Kaye, written in 1908, but first presented on Broadway in 1911. It is based on Nathaniel Hawthorne's short story, Feathertop, but greatly expands the tale. Although it had what we would now consider an extremely short run in New York, it was filmed as Puritan Passions during the silent era, has been revived twice in New York (most recently in 2005), has been made into an opera, and has become a favorite of universities and local theatres.
