(During this musical section, Don Preston, chemically altered via macrobiotic snack consumption, is transformed into a Phantom Of The Opera-like monster. While members of the robot combo hiss and boo him, he sneaks around behind the stage set-up, planning a terrible revenge for the rejection of his electronic music. He pounces on the unsuspecting Underwood in the midst of his rapturous piano solo, strangles him, throws him to the floor, and takes his place on the bench. The final revenge? He spews forth a morbidly diatonic piece, entitled SELL US A PRESIDENT, AGENCY MAN.)
