Guthrie's singing partner on KFVD radio in Los Angeles was not named Memphis Sue. Her real name was Maxine Crissman, and she was known as "Lefty Lou," because she shared Guthrie's politics and was just as outspoken. In fact, Guthrie was never pressed to stop singing union-organizing songs; the station owner, Frank Burke, was a populist New Dealer who agreed with Guthrie. The reason Woody was fired was because after the Soviet Union signed a non-aggression pact with Nazi Germany in 1939, he started singing songs that, mirroring the Communist Party line, denounced the war as a capitalist fraud.
