After doing some due diligence, I recall that the song was indeed authored by two fellow former residents of Fresno, CA, Ed Rush and George Cromarty. I once dated the latter's sister, just prior to entering the Army (no, she wasn't the reason). George later became quite a new age guitarist, I understand, though I have no idea where he is now. I think Ed Rush is still about. He may have posted a comment in the past. This is one of those songs people just grabbed and modified to suit themselves. Does anyone know whether the movie credits the composers?
