Dammit, THEY DIOD CONTRIBUTE GREATLY TO THE RE-POPULARIZATION OF FOLK MUSIC. They did sing sourly but there was a lot of good material for new folksingers (who's singing , I hope was not sour)

I was still in the USAF (career type) and had been doing my own "civil rights" progrm. (I had the first integrated C&W group to record for a major lable, in 1959) when I first heard Peter Paul and Mary. I was driving into Sacramento from Mather AFB when I heard their "Blowing in The Wind" on an AM "Pop" station. "Finally", I thought to myself. I was so overcome by emotion that I had to stop the car and sit by the side of the road because I couldn't see clearly enough through the tears.
