Pete Seeger, the granddaddy of the folk-protest movement turned out traditional folk songs of the underclasses and new songs with messages of peace, love and social justice played on simple chords; He was also one of the earliest champions of the young Bob Dylan, 22 years his junior, who would go on to become a reluctant 'voice of a generation' and one of the first true legends of popular music. The causes Seeger and Dylan championed over half a century ago may not burn so brightly in our collective conscience in these inward-looking days of social networking, but the words they wrote still resound. Their influence on the music of the last 50 years is impossible to overestimate.
