"Trapeze"

I've been listening to Argent a lot lately.  Over the last month or so, I listened to Circus four times, and somewhere along the way, I realized something about "Trapeze."  At ~0:56 and again at ~6:49 there are sections that really exploit the stereo mixing, with electric piano (I'm pretty sure it's a Fender Rhodes) panned far left, bass centered, and guitar panned far right.  Musically, these alternate so that there's something of a sense of the music moving back and forth from left to right.  Extra-musically, this seems to present the movement of the singer/speaker's act.
