The Black Plague

This isn't the Black Plague that you're thinking of!

The sickness, it creeps
As we all sleep
And takes us in the night
It will not stop
It cannot stop
It takes us by surprise

By morning, we're dead
Lying still in our bed
And it travels on to seek it's next prey
I give them my sympathy
As there no life left in me
They'll be dead before the next break of day
