Many of the players heard went on to successful postwar careers in jazz. It's been reported that, after some traveling, "Charlie", Karl Schwedler (1902-1973), died in Germany. Other sources claim he emigrated to and died in the USA.
These are all spins on American pop songs with special, perverted lyrics.
