Stravinsky's incident with the Boston Police

Stravinsky's unconventional dominant seventh chord in his arrangement of the "Star-Spangled Banner" led to an incident with the Boston police on 15 January 1944, and he was warned that the authorities could impose a $100 fine upon any "re-arrangement of the national anthem in whole or in part". The police, as it turned out, were wrong. The law in question merely forbade using the national anthem "as dance music, as an exit march, or as a part of a medley of any kind", but the incident soon established itself as a myth, in which Stravinsky was supposedly arrested, held in custody for several nights, and photographed for police records.
