About health conditions, they could do show a la "The Dance", or "One Night Only", or a short tour in specific cities, it would be low risk for them.
But it's too late. The magic is not there any more, the bag is full of rocks again, and the voices are gone. I wouldn't pay an expensive ticket to watch them, I think I wouldn't go even if I win a free ticket. I don't want to hear those embarrasing voices, and if there are again those "silver springs" looks between S&L, that would be ridiculous and more embarrasing.
