This has been driving me nuts. I remember a song from back in the 70's about Gettysburg and have been trying to place who did it. It was by a British band for sure and I was thinking either Greenslade or Colosseum for some reason but I have been through the respective disographies and can't find anything.
I recall lyrics were approximately "Rusty black cannon fired only in my mind, questions left unanswered by a century of time."
Any ideas?
