Years later in the early 80's (I think) I attended a Peter, Paul and Mary concert at Saratoga Performing Arts Center. I was in the third row, and at one of the song breaks, Noel and Peter bantered on about getting older and losing their hair. Peter caught my eye, pointed to me and my bald head, and said, "This guy knows what we're talking about!" I was absolutely thrilled.
I have always loved, and will always love, PP&M. Mary's voice had a quality that just couldn't be duplicated (though Mama Cass came close). Rest in peace, Mary Travers.
