I don't think the backstory really dignifies anything, or solves any problems that you tried to solve during the recording.Tom Waits
"Oh, this is all based on the John Wilkes Booth story, and that third song is when he was trapped in the barn." I mean, I could tell you anything. "Helen Keller made an appearance in the last tune, and it's sung by her mother." "Oh, okay."
Your mind will make sense of anything.
