"The Nazis on the one hand would jam transmissions from the Allies' stations, but on the other hand would also copy them. The band Charlie and His Orchestra is considered as a negative example, also called Mr. Goebbels Jazz Band. Several of Germany’s most talented swing musicians, such as saxophonist Lutz Templin and vocalist Karl “Charlie” Schwedler, were active in a Jazz band. Here the Nazis replaced the original texts with their own provocative propaganda texts that were pro-Nazi and anti-American/British. For example, the lyrics for “Little Sir Echo” has anti-American/British appeal with lyrics such as “German U-boats are making you sore, You’re always licked, not a victory came through…You’re nice, little fellow, but by now you should know that you can never win this war!” Goebbels’ propaganda was broadcast over pirated short-wave frequencies into America, Britain, and Canada in order to spread fear and weaken the morale of Germany’s enemies (WFMU Staff).
"The situation intensified in 1942 with the entry of the United States in the war. For diplomats of foreign embassies and Wehrmacht members, a couple of jazz clubs continued to remain open in Berlin. In addition, individual, illegitimate venues and private parties still played jazz. In 1943 jazz record production was stopped.
The Swing-Jugend, or Swing Youth, was a movement among mainly youth from 14–20 years old who dressed, danced, and listened to jazz in defiance of the Nazi regime. The Nazi party acted against this movement by detaining several of the young leaders of the Swing Youth and sending them to concentration camps. However, the Swing Youth continued to resist the Nazi party by participating in prohibited swing and jazz activities (Neuhaus). Charlie and His Orchestra was moved in the still bombproof province. Jazz was also incorporated into musical works such as operas and chamber music through “art-jazz,” which utilized jazz-inspired and ragtime-inspired syncopated rhythms and modes. Famous operas such as Krenek’s Jonny spielt auf! and Boris Blacher’s Concertante Music for Orchestra are examples of art-jazz (Dexter)."
