Final answer:
The socialist folk singer, train-hopper, and labor organizer called 'the Golden Voice of the Great Southwest' was Woody Guthrie.
Step-by-step explanation:
His given first name was actually Woodrow Wilson Guthrie, but he was commonly known as Woody Guthrie.
Guthrie rose to prominence in the 1930s and 1940s as he used his music to express his support for the rights of workers, poor people, and those affected by the Great Depression. He wrote numerous songs about social and political issues and became an important figure in American folk music.
Some of Guthrie's most well-known songs include 'This Land Is Your Land,' 'Pastures of Plenty,' and 'Deportee (Plane Wreck at Los Gatos).' His songs often reflected the struggles and experiences of ordinary people.
