“You’re a Grand Old Flag” is an American patriotic march. 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 his stage musical George Washington, Jr. The song was first publicly performed on February 6, the play’s opening night, at Herald Square Theater in New York City. “You’re a Grand Old Flag” quickly became the first song from a musical to sell over a million copies of sheet music. The title and first lyric comes from someone Cohan once met; the Library of Congress website notes. “You’re a Grand Old Flag” would go on to become one of the most popular U.S. marching-band pieces of all time. The original lyric for this perennial George M. Cohan favorite came, as Cohan later explained, from an encounter he had with a Civil War veteran who fought at Gettysburg. The two men found themselves next to each other and Cohan noticed the vet held a carefully folded but ragged old flag. The man reportedly then turned to Cohan and said, “She’s a grand old rag.” Cohan thought it was a great line and originally named his tune “You’re a Grand Old Rag.” So many groups and individuals objected to calling the flag a “rag,” however, that he “gave ’em what they wanted” and switched words, renaming the song “You’re a Grand Old Flag”.In the play itself, the scene with the Civil War soldier was replicated. The soldier’s comment was the lead-in to this song. Thus, the first version of the chorus began, “You’re a grand old rag / You’re a high-flying flag”. Despite Cohan’s efforts to pull that version, some artists such as Billy Murray had recorded it under its original title, “The Grand Old Rag”, in advance of the play’s opening, and copies under that title still circulate among collectors. Cohan’s second attempt at writing the chorus began, “You’re a grand old flag / Though you’re torn to a rag”. The final version, with its redundant rhyme, is as shown below.
Today, many different arrangements of the song exist. In particular, Paul V. Yoder’s 1954 arrangement of “You’re a Grand Old Flag” is a version commonly used today by the U.S. military in its performances of the song
