Here's one I picked up recently.

I've been a rambling all of the time
For the best part of 2 years
Foreign secs, they come and go
And they bring me little cheer.

I've got a pot in an offshore bank
It's all my heart's desire
As soon as we've bled the country dry
I'll be able to retire.

So rise up, rise up, you people all
It's too late now revolting
The stable doors are open wide
And the horses all are bolting.

And now my song is almost done
I can no longer stay
The fatcats have stashed their loot abroad
And they thank Theresa May.
