The original version is especially dear to me. It has always my favorite song since it came out. A classmate of mine a very good friend and Green Beret, oddly enough, started a two person group after the Vietnam war and I swear they could sing as well or better than Simon and Garfunkel. The odd part was I never heard him sing a note until he returned. Funny what things like war will do to you. As amazing as that was I don't think all of him ever made it back. I lost track of him and never saw him again. Through those years I thought a lot about that song, still do.
