Peter Yarrow is one-third of the famous folk trio, Peter Paul & Mary. I’ve been a fan since the sixties when I attended a concert of theirs at The Hollywood Bowl. That concert was my first date ever. I was a young 15-year-old going out with a mature 16-year-old. I spent the entire concert working up the courage to put my arm around her shoulders as we sat, side by side, singing along to “Blowin’ in the Wind” and “If I Had a Hammer.”
