This is easy.

It's raining
Its pouring
The old man's asleep
If I should die before he wakes
I pray my soul to keep
On running
Keep on running
Keep on running
Keep

It's pouring
It's raining
The old man is dead
Take your hands and cut them off
And put them on your head

It's raining
It's sleeting
We all fall down
We scream and hoot and holler
Because the circus is in town

It's pouring
It's raining
With a pocketful of rye
It's taking all my willpower
Not to end this:
"Then we die"
