You're A Grand Old Flag

"You're a Grand Old Flag" is a patriotic song of the United States. The song, a spirited march written by George M. Cohan, is a tribute to the U.S. flag. In addition to obvious references to the flag, it incorporates snippets of other popular songs, including one of his own. Cohan wrote it in 1906 for George Washington, Jr., his stage musical.

"You're a Grand Old Flag" quickly became the first song from a musical to sell over a million copies of sheet music. The song was used in a major production number in Cohan's 1942 film biography, Yankee Doodle Dandy.
