On this edition of ST, we speak with Dr. Mark Allen Jackson of Middle Tennessee State University. He's an expert on political expression in American folk music, and he's also the author of "Prophet Singer: The Voice and Vision of Woody Guthrie" (University Press of Mississippi). Dr. Jackson will be giving a talk at the Woody Guthrie Center in downtown Tulsa this coming Saturday, the 26th, beginning at 7pm. The lecture is entitled "Woody Guthrie as Political Humorist: His Influences, Expression, and Legacy," and it's free to the public. Guthrie, of course, didn't just write songs and poems about America's working poor, immigrants, downtrodden, and disadvantaged -- he also created political cartoons and newspaper columns championing these same people. Indeed, as America's fiscal suffering amid the Great Depression gave way to its economic thriving during World War II -- and as Guthrie's own popularity and influence in our national culture concurrently increased -- the Bard from Okemah created more and more political texts and commentaries.
