Dylan has more popular songs. He even has songs that are musically and lyrically superior to this one. However there is no song in his impressive oeuvre that had a greater impact.

This song, chronicling the misjustice accorded to Ruben Carter, created such a cause celebre that it would ultimately lead to his exoneration. THAT is the power of music. It was this song that truly introduced me to the world of protest music over 20 years ago.
