He's 2/10 for me. Jon doesn't only have issues with his voice but also with his confidence and passion. But after the last leg, he's rejuvenated. The confidence was suprisingly high and same goes to the passion too. This is something that I haven't seen since RS left so my praises to Jon. But as I replay the performances during that SA leg, it's very clear that he's driving himself further. Yeah it's the last 2 shows anyway but it could lead to a very rapid decline if done more often. He's still struggling to sustain high and long notes without cracking his voice. But I really hope that Jon will prove us wrong again nexy year because this is something that he's good at.

This one is like a cheer up performance. Hearing him getting the crowd alive with the classic "Oh yeeeeaaaahhh" was damn painful. But Jon makes up for it by a lively and raspy second verse. AND THIS WAS BACK IN 2015.
