The demon went down to Cardiff
Things were not on an even keel
He stood by the lift at the space-time rift
'Cause he wanted to make a deal.

When he finally met the Captain
(In the flesh rather than in Hell)
Crowley smiled at Jack, introduced himself
and said, "Now Harkness, listen well:

"I know you don't remember
What it's like to be down below
A quick visit and then you split
That's how it always goes.

"These circumstances are not ideal
For you it's become old hat
And I'm seeing red because you won't stay dead
But one contract can change all that."

Then Jack said, "Alright Crowley
But give me a free pass
Just until I learn that I won't return
And I need to cover my ass."

Captain, you'd better watch yourself! Be careful what you do
This 'Crowley' sure means business and the Doctor can't help you
You've been immortal since the Bad Wolf brought you back to life
But everyone knows that came with a price!
