According to Cranky Yankee: "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."1959, Cranky?
Peter, Paul and Mary say that they first met each other in 1961.
Bob Dylan wrote "Blowin' In The Wind" in 1962.
Peter, Paul and Mary recorded "Blowin' In The WInd" in 1963.
1959? I don't think so.
