Thanks Leveller for filling in the background with Paul Jones's battle. I knew a little but all that detail was fantastic.
I did at one time know the reason why the Pierce was in the song rather than the Serapis but I've forgotten & at this point won't even venture a guess. I'll ask Jeff Warner if he knows when I see him Friday, maybe I won't sing it (unless he doesn't), it was one from his father's collection.
