Labor's Troubadour traces the life and work of labor balladeer Joe Glazer. For more than half a century, armed only with his guitar, reams of songs, and conviction, Glazer has marshaled the power of music to fight for union representation in mills, mines, factories, and offices all over the country. A performer, educator, and "musical agitator for all good causes," Glazer has sung on picket lines, in worn-out union halls, and at elegant dinners, using humor, irony, and pathos to drive home the message of unionism.
