A Question for the Braintrust

So, with the recent news of the death of Idi Amin, I've had the old song "Idi Amin" stuck in my head (it was in frequent rotation on Dr. Demento's show in the 80s; I have no clue who sang it). So I'm now looking for the lyrics, but no google search I've tried has borne fruit.

Does anyone remember the song I'm talking about? Know who performed the song? Know where I could find the lyrics?
