Here's one from East Coast Story:

There are three verses in which three politicians are trying to get sit-in demonstrators to move. I know the last two politicians are Ronald Reagan as then Governor of California and President Nixon.

The tune is "Officer Krupke" and here is the Reagan verse:

Dear kindly Ronald Reagan
Forgive us if we're frank
We saw you on the late show
Like man, you really stank
You lost one for the gipper
You bombed in Brother Rat
Sacra-mento
Now look where you're at'

Dear Governor Reagan
We just gotta say
Perhaps your worst performance
Is your one here today
We'd like to oblige you
But one thing is clear
You've laid an egg
So we'll stay here

We'll stay here
We'll stay here
We'll stay here, here, here
We're sincere
When we say we'll stay here!!

I just remembered the third "politican" - it was J. Edgar Hoover
and remember the second part of the verse:

Dear J. Edgar Hoover
We won't go to jail
We've got a real smart lawyer who will free us on bail
Before we're convicted
And tossed in a cell
We'll heist a plane
And join Fidel!

Join Fidel, join Fidel, we will join Fidel
What the hell
We'll split and join Fidel!!
