Go to hell!
There, that's 3 words!
Gene and Paul have said that no individual is bigger than the band, including themselves. Sure, they were really talking about Peter and Ace and that was their way of justifying replacing them and continuing on. Gene in recent years has said that he would like to see the band continue on without him and Paul once it comes time to hang it up. Now I don't know if he was serious when he said that, but knowing Gene, if there is a way to make a buck, he would absolutely be down for this. Paul on the other hand would not be. He may have "agreed" to this idea, but I think it was only to placate Gene's ego so as not to upset the apple cart, especially during this rebirth of KISS.
Why wouldn't Paul be down for this? Well, I think that securing his legacy is a big issue with him, even if he has never gone on record as saying as much. He is the consummate showman and I think having some other 'wannbe' preening and strutting as his "official" replacement just would NOT sit well with him. Gene on the other hand would just cash his checks and be content.
But when it comes down to it, when that moment finally arrives where they have to make a decision, I do believe that they would wise up, say their goodbyes and close up shop permanently once and for all.
Fast forward 2 months as Gene and Paul announce the 'One Mo Time Tour' with Peter and Ace back in the band. Whichever way they choose to end it, it will involve both Peter and Ace for one last show, if not a complete Tour. I'm guessing that it will be a series of shows at MSG.
Okay, that was more than 3 words. Choke on my manifesto!
