Really the refrain, "Nobody's gonna take my car, nobody's gonna steal my girl", would be the agitation, the "Uuuuuuuuuhhhhhh" you hear before the organ solo is the spin which the organ solo could sure complement, and the thudding bass at the end seems to be the machine shutting down...
I guess I would have to some how make a video of all this going on, really, but I had the two things playing simultaneously at one time or another, if not only visualized this during my Deep Purple fan phase which found me having one of the last new copies of MACHINE HEAD, amongst the rest of some their stuff which I only had on a few cassettes...
