The Brandos' "Gettysburg" was one of my favourites when I was DJing at WLUR-FM in the late 80s.
The battle's last and bloodiest day was 150 years ago today. I used to spend a lot of time at Gettysburg, and on the banks of Antietam Creek near Sharpsburg, Maryland. These are two locations that rather bolster the traditional Native American view that whatever happened at a place is in a sense always happening at that place. Or, as William Faulkner put it, "The past is never dead. It's not even past."
