They're Coming To Take Me Away Ha Haaa B-side by Napoleon XIV.
This is not the quirky song you heard on Dr. Demento's famous radio show about a man spiraling into utter madness. This is the madness.
You have to loop it for about 45 minutes to get it.

I've been searching- without knowing- for awhile to put a tag on "things". This nailed it.
When I'm not listening to this, I'm listening to Beatles Rubber Soul and Revolver studio cuts that didn't make those albums- Day Tripper, We Can Work It Out, Rain, etc.
