Blowin' or Blowing in the Wind info:
"Blowin' in the Wind" is a song written by Bob Dylan in 1962 and released on his album The Freewheelin' Bob Dylan in 1963. Although it has been described as a protest song, it poses a series of rhetorical questions about peace, war and freedom. The refrain "The answer, my friend, is blowin' in the wind" has been described[by whom?] as "impenetrably ambiguous: either the answer is so obvious it is right in your face, or the answer is as intangible as the wind".
In 1999, the song was inducted into the Grammy Hall of Fame. In 2004, it was ranked #14 on Rolling Stone magazine's list of the "500 Greatest Songs of All Time".
Peter, Paul and Mary:
Peter, Paul and Mary were an American folk-singing trio whose nearly 50-year career began with their rise to become a paradigm for 1960s folk music. The trio was composed of Peter Yarrow, Paul Stookey and Mary Travers. After the death of Mary Travers in 2009, Yarrow and Stookey continued to perform as a duo under their individual names.
Mary Travers has said she was influenced by Woody Guthrie, Pete Seeger, and the Weavers. In the documentary Peter, Paul & Mary: Carry It On — A Musical Legacy members of the Weavers discuss how Peter, Paul and Mary took over the torch of the social commentary of folk music in the 1960s.
