<Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> <P> "The Stars and Stripes Forever" is a patriotic American march widely considered to be the magnum opus of composer John Philip Sousa . By a 1987 act of the U.S. Congress, it is the official National March of the United States of America . </P> <P> In his autobiography, Marching Along, Sousa wrote that he composed the march on Christmas Day, 1896 . He was on an ocean liner on his way home from a vacation with his wife in Europe and had just learned of the recent death of David Blakely, the manager of the Sousa Band . He composed the march in his head and committed the notes to paper on arrival in the United States . It was first performed at Willow Grove Park, just outside Philadelphia, on May 14, 1897, and was immediately greeted with enthusiasm . Following an Act of Congress in 1987, it was officially adopted as the national march of the United States of America . </P> <P> Historically, in show business and particularly in theater and the circus, this piece is called "the Disaster March ." In the early 20th century, when it was common for theaters and circuses to have house bands, this march was a traditional code signaling a life - threatening emergency . It subtly notified personnel of emergency situations and ideally allowed them to organize the audience's exit without causing the chaos and panic that an overt declaration might . Circus bands would never play the tune under circumstances other than impending disaster . One memorable, if heartbreaking, example of its use was during the Hartford circus fire of July 6, 1944 . At least 168 people were killed, though some estimates are much higher . Numerous bodies burned so badly that they were either unrecognizable or completely incinerated . </P>
