That's very nice Becky.


By the way {_Warrior_} his voice is slowly (Or maybe not slowly) coming back to what it should be, his bad mental (Obviously not saying he's crazy) stuff are going away.
And yes confidence issues can cause worse singing, performance (Not just concerts), etc overall (or just affect one thing or two, etc.).

Jon doesn't move and isn't energetic ---> Audience doesn't like it ---> Jon sings worse due to confidence.

Jon moves and likes it/energetic --- Audience likes it more ---> Jon sings better due to higher confidence.

People seem to not wanna accept that confidence issues or mental stuff can cause problems in terms of performances, etc.

His confidence issues after Richie left seemed to become so bad that I can see in the videos that he stopped using correct breathing technique (Incorrect or correct though, it won't change how you sound like. Just for more endurance and less strain on vocal cords, etc).
