Drawn from his seminal Folkways recordings, these songs bear out Pete Seeger's commitment to social justice, human rights, organised labour and the antiwar movement—all of it risky territory in the late '50s. Listen to "Which Side Are You On" and you can still hear the Establishment quaking. The title song appears twice: First in a modest 1956 version with just him and his banjo, then in a live one from four decades later, with thousands of voices singing along. That's Seeger's career in a nutshell.
