Pete Seeger was one of the great social justice protest singers.  His songs ("If I had a hammer" for example) were legendary.  Pete believed that music could change societies.  He never gave up, even during the long period of time when he was blacklisted.  Then in 1968 he appeared on The Smothers Brothers Comedy Hour and introduced a new anti-Vietnam war song.  It was "Knee deep in the Big Muddy."  This is the story of Pete's life, and of what happened when he sang that song on the Number One television program of the age.
