yeah, sounds like someone in motor city got their wires crossed.
here's the link for the story at the Detroit News:

Scroll down until you see the club name "Old Miami."


HOWEVER...

The Detroit Free Press tells a different tale for that same night,
same club:

Quote:
The Old Miami
April 22: Euphoric Haze, Jerrycan, Vietnam Prom, My Left Arm, Larry
Bone Band


It looks like someone interposed "Larry Bone Band" and "Ass Ponys."
Easy mistake, I do it all the time.

I'm gonna call someone in Detroit as soon as I can find a number to
the Conference.
