Oh darling, sweet darling
you must not have fear!
The sins and crimes
of those many times
have brought Gods wrath down here

But darling sweet darling,
you mustn't shed tears
for the plague doctor is here!

He'll rid you of sickness
He'll save you and me!
He'll cure us, I promise you see?

With incense and spices
His quick remedy
He'll bleed us both out
And set us both free!

Written by me :3

The so called Black Plague lasted from 1348-1350, and took around 137 million lives. Plague doctors were one of the many unfruitful solutions at the time.
