Looks like Motogrrl found the lyrics and posted them on her own blog but didn't post them here.

THE BALLAD OF J. EDGAR HOOVER
Words: Holly Tannen, copyright 1990.
Tune: "Joe Hill" by Earl Robinson copyright 1938.

I dreamed I saw J. Edgar Hoover
'Live as you or me
"But J.," I said, "You're ten years dead."
"I never died," said he.
"I never died," said he.

"For forty years, by fear and greed
You ruled the FBI
But now we've taken back our rights!"
Says he, "I did not die."
Says he, "I did not die."

Where phones are tapped and lists are kept
And documents are shred
Where statesmen and reporters lie
It's there you'll find J. Ed.
It's there you'll find J. Ed.

Where poor folks fear to speak their minds
And live apart in dread
Where crimes are blamed on innocents
It's there you'll find J. Ed.
It's there you'll find J. Ed.

And standing there as fat as life
With beady little eyes
"So if you think I'm dead," he says
"Just try to organize
Just try to organize."

I dreamed I saw J. Edgar Hoover
'Live as you or me
"But J.," I said, "You're ten years dead."
"I never died," said he.
"I never died," said he.
