On review of the artists listed here am surprised no one has mentioned Steve Goodman as yet. One of several folk artists of the Chicago area in the late '60s early '70s, along with John Prine. If you aren't familiar with his music, and enjoy John's songs, check out Steve. For those unaware he wrote "City of New Orleans", the best know recording of which was by Arlo Guthrie, another stellar singer/song writer/storyteller.
