RECOVERED HISTORY: STRAVINSKY ARRESTED IN BOSTON FOR HIS ARRANGEMENT OF THE NATIONAL ANTHEM
DC Musica Viva - On April 15, 1940, Stravinsky's unconventional major seventh chord in his arrangement of the Star-Spangled Banner led to his arrest by the Boston police for violating a federal law that prohibited the reharmonization of the National Anthem.
Wiki Answers - In Boston, Stravinsky conducted a performance of his arrangement of the American National Anthem, which he dedicated to the American people and allowed it to be used freely. Massachusetts had a law against the tampering of national property. They considered the anthem national property, and his genius arrangement "tampering." They seized his score and took him away. . . Luckily, he was released after he convinced authorities of his good intentions.
