The Plague Dogs- Snitter

I read The Plague Dogs awhile ago and I always liked the poem/song that Snitter tells throughout the book

Words- (because my hand writting is bad)

You were disturbed inside your head
And thought to clean the cobwebs out
There will be none when you are dead
The skull untroubled, have no doubt
and you will learn to do without
The flesh and blood quotidian
Refined to nothing, bleached to nowt
Need seek no more your vanished man
