Wrestlers have to walk right in front of the sound guy on their way to the ring. The sound guy is at the gorilla position.
When on Confidential they did a 'Behind the Scenes of RAW' thing where you got to see how they put the show together, how the writers jotted down their idea on a napkin 5 minutes before the show started, and even the multi milliondollar production truck! They showed the sound board and all the buttons that cue Titan Trons and Music. Bischoff was like "Cue Bischoffs music! now cut his music! Cue his music again!" and the guy was just pushing a button out of a HUGE pannel to do it in the truck.
So no.....
And TEST~! could have been in the truck screaming "PLAY THE MUSIC TO DISTRACT HIM MONKEYS!"
Well then maybe someone at the gorilla position says "OMG Steiner is here and he's coming out!!" through a headset to the production truck guys?
