Imagine this ok?

So you're at one of the stadium concerts and the shows about to start, the stadium is dark GNR is about ready to explode onto stage, so all of a sudden you hear something that hasn't been said at a GNR show since 1993 and it's extremely loud, the voice screams in a very low loud voice "YOU WANTED THE BEST WELL THEY DIDNT FUCKING MAKE IT SO HERES WHAT YOU GET FROM HOLLYWOOD GUNS N' ROSES", then there's another very strong voice right after that and this one says "YOU KNOW WHERE THE FUCK YOU AREEE, YOURE IN THE JUNGLE BABY WAKE UP ITS TIME TO DIEE" the whole stage lights up slash starts ripping the opening riff of Jungle and What's that sight you see on stage? You think to yourself damn why does Frank Ferrer not sound awful anymore and so you look and you see it's not Frank Ferrer. Well who is it you think to yourself. Then the realization hits you that beating the shit out of the drums is none other than Steven Adler and then you notice another sight on stage you notice that there's no Richard Fortus, and that the man playing behind slash is none other than Izzy fucking Stradlin. How would you guys feel if this happened?
