Yes, the short one's title is 'The Ballad of Spiro Agnew'. Both can be found on the 'Politics' live album - hilariously funny!

There are a few differences between the version DDPro posts above and the album:

V.3 l.2: 'He likes being in Rolling Stone'
V.8 l.1: 'Kennedy' instead of 'Jimmy Dean'
V.13 l.3-4: He came back and tried again
But now he's gone to find some peace
V.14: He'll go back to Colorado
For a little while and then
Just as soon as he gets horny
He'll be coming back again
