Someone uploaded that episode of Livewire where JR is visibly in a bad mood to YouTube. I guess calls weren't being screened as the majority of them were about WCW which Jim speaks very candidly about. I know Vince probably didn't even know Livewire ever existed but it's crazy this all made the air.
And for what it's worth, that two minute clip of JR from this show really showcases the only time he was unpleasant. JR was pretty professional for the majority of the program. He even comments on the Sid/Arn scissor fight!
Vince was a guest on one of the first episodes of Livewire, the one where Paul E. calls in. And JR was doing his semi-heel gimmick at the time so this was all in character.
Hall worked for Dusty in PWF a few months before this...I have to wonder if he was the one to tell him to go full Magnum TA with the hair? (Yes, I know he was "Magnum" Scott Hall a few years earlier when both were ripping off Tom Selleck)
