The Legacy of James Shelby Downer

When did King Kill become King Kill? Was it a bunch of works that had been put together? Who was responsible for pulling it all together and giving it the title? I could see the echoes of the footprints of James Shelby Downer. What year was that all pulled together? Do you remember? 76, 1976. The Hidden Faces of American Earth Script by Jim Brandon are both labeled out of print on Amazon.
