I Thought these days vocally was decent considering its a really hard song and was one off performance. i thought it was a small improvement but the rest of the songs i listened to were bad...

if jon manages to improve 10-20% it will make a big difference because he has confidence issues as well...his timing is off his breathing is off cause he worries too much if he will hit the note...the guy didnt forget suddenly how to sing , i cant imagine how hard it will be for him
