I used to know someone who sang about
"Babylon is fallen, fallen, fallen.
Babylon is fallen, to rise no more".
And something about "the watchmen publish peace".
Which ,when I asked him, he said it came from the Civil War, but gave no detail, so I can't back this up at all. For what it's worth.

I'm also dubious about calling it "English". The Scots were all over it.
