Is Jon trying to scream?

Hey guys,I was just watching some live performances of Livin in Sin and I stumbled across this performance from 2011 from San Sebastian

At 4:00 you can see Jon opening his mouth pretty wide but he doesn't make any sounds untill 4-5 seconds later.What do you guys think he was tryin' to do?

he's hungry and wants to eat the mic, then he realizes everyone can see so he doesn't

It's just the typical "aaaaah" that he always used to do at that part of the song during recent tours. Most of the time he stepped back from the mic a little when he started it, either due to him worrying about not getting into the right key or him thinking it would be some cool sort of "fade in-effect"...

Aloha !

He's started doing that since 2008 or something. What's basically doing is trying to hit a note before the mic can pick it up, once he's at the right key he gets closer to the microphone and then it'll sound like he's hitting the note perfectly fine.

Salaam Aleikum,
Sebastiaan

Well I can hear what he is "singing" before coming back to the mic. It's low but audible. Am I listening to music too loud?
