Well, I've had a good look through this thread and I'm settling for this quote "Poetry is sometimes best left unexplained, because explanation limits imagination" from some genius, further up.
I'll be dropping the "Shell Shock" story from the intro. I picked that up from Max Ferguson's show years ago.
The song tells enough of a story, all by itself and is relevant to many, without the need for explanations.
Thank you all.
Jim
