I found a very nice Travis Edmonson recording of the song here (click). Apparently, Bud & Travis sang this song on the floor of the U.S. Congress, and it was entered into the Congressional Record.
The Edmonson recording isn't the same as the Limeliters, but it helped me understand a couple of parts that were unclear in the Limeliters recording - most notably, the phrase must be:

all was still, all was gone

I made corrections in the lyrics I posted above.
