I feel like these two S.America shows are definitely a step up from the first N.America shows. A lot of debate is still going on about Jon's voice and I've learned to agree with the fact that it's simply shot (his mental well-being most likely also adding to it). I'd also like to just throw in my two cents about his lack of mobility. In my opinion it might just simply be about lacking the energy. He is 55, he's aged really gracefully but maybe these past three years just hit him physically to the point to which he doesn't anymore want to jump about and stuff. Jon looks pretty exhausted at the end of shows these days. If he'd give as much energy as he had in 2011 or what not he would last about 10-15 songs as singing also absorbs a lot of energy.
Just wanted to give me two cents about this whole thing. I'm really hoping that they can do an European tour, which will happen unless something goes wrong with this tour at the moment. I'd still be happy to see them just to see them play some of the songs that mean so much to me.
