This came into my head today, and sort of grew. I've been using the tune of Denomination Blues (as I heard Ry Cooder sing it).

Please feel free to add some verses if any occur to you.

Credit Crunch Blues

Well, I'm watching the news, on my TV
And they tell me that things are as bad as can be
Prices going up and shares going down
All in the toilet going round and round
And that's all
I'll tell you that's all
Here comes recession
I'll tell you that's all

They say it's subprime lending brought the credit crunch
Now maybe they see that there's no free lunch
And that's all
I'll tell you that's all
Here comes hard times
I'll tell you that's all

Well the bankers dug a hole, then they fell in
Now they're selling us a shovel, to dig' em out again
And that's all
I'll tell you that's all
Here comes depression
I'll tell you that's all

Well the banks and markets going all to hell
If they all go down, we'll be going as well
And that's all
I'll tell you that's all
Hello, Mr Satan
I'll tell you that's all

They nationalise one bank, they nationalise two
Don't stand still, or they might nationalise you
And that's all
I'll tell you that's all
Here comes the Thirties
I'll tell you that's all

Worried 'bout your cash, keep it under the bed
Need to fill a suitcase to buy a loaf of bread
And that's all
I'll tell you that's all
Here comes inflation
I'll tell you that's all

Well, I've got no answers but I tell you it's true
One law for them and another for you
And that's all
I'll tell you that's all
There goes the future
I'll tell you that's all
