Peter Yarrow has been one of the planet's most famous folk singers for nearly 60 years, having started with Peter, Paul and Mary back in 1961. He's still performing solo and with Paul today, with songs like "Blowin' in the Wind" and "Puff the Magic Dragon" still striking chords with audiences. He's also impressively an anti-bullying activist with his group Operation Respect now bearing 22,000 chapters across America, in 70 percent of Israel's schools and other countries beyond. He sat down with Koz for a wide-ranging Kozversation about his storied career and why he still feels he has something to say.
