&amp;#8220;The folk-singer and radical song-writer Woody Guthrie was born 100 years ago today - July 14th 1912. His biographer Joe Klein celebrates the centenary with a road trip, listening along the way to a few of Woody&amp;#8217;s 1,000 songs, to his recorded interviews and to the voices of his friends and family.
Joe Klein is also the author of &amp;#8216;Primary Colours&amp;#8217; and a correspondent for Time Magazine, so he&amp;#8217;s taking the political temperature in some of the battleground states as the 2012 Presidential election campaign warms up.
In a journey that takes him from his Washington bureau to Philadelphia, Pittsburgh, Charleston West Virginia and beyond, Joe listens to the concerns of the voters. He discovers that Woody&amp;#8217;s messages to America, written and sung during the depression and World War 2, can still cut to the bone.&amp;#8221;
