By Woody Guthrie
Woody Guthrie was labor's foremost troubadour during the 1940s and 1950s. He could be found at demonstrations and on picket lines all across the country, supporting the struggles of working men and women with his inspirational, often cutting lyrics. The author of such classic songs as "This Land is Your Land" and "Hard Travelin'," he inspired a generation of younger musicians ranging from Bob Dylan to Bruce Springsteen to John Cougar Mellencamp.
