Horst Wessel
The New York Youth Symphony abruptly canceled the Carnegie Hall performance of a piece it had commissioned after it was discovered to include a 45-second musical quote of the "Horst Wessel Song", written by "Sturmführer" Horst Wessel, a district leader in Hitler's "Sturmabteilung" (SA). An anthem of the Nazi Party from 1930 to 1945, it is now banned in Germany and Austria.
