I think it is all over for them as a live act,I saw them on all their tours up until Bounce and they were always a great live act.After a break until their last your I was shocked that he couldn't even sing a note.As has been said I think he might have some health problems.The only other major singer I can think of that has had such a drop in quality is Meat Loaf and he has wisely retired from touring.Last few times I have seen Kiss Paul Stanley has sounded really rough but at least he can still hold a tune,put on an energetic show and allow Gene to do a lot of the heavy lifting vocally.Perhaps after a 2 year rest and with Richie back they could maybe manage a farewell tour but I doubt it.
