'Which side are you on?'

Pete Seeger -- folk singer, relentless advocate for peace and for the working man, and American icon -- died today at age 94. Like Harry Truman famously said, it's a damn shame when anybody dies, but we should wish to live one-quarter as full a life as Seeger, whose career began before World War II and lasted into Barack Obama's presidency. How relevant are the words that he sang into today's world? Listen for yourself....to "Which Side Are You On?"
