Pantera' s Vulgar Video doubt

[Ecto]

Please, help me.

I think it's in the end of this video that appears Pantera playing with many other bands and there's a moment that shows Rob Halford singing.

My question: which song he is singing? How plays it?

Thanks a lot.

Yeah I remember that part, but I have no idea what the hell he was singing. Rob Halford is awesome though, and I'll get to see him in concert in a week.
