Songs with key change

Can't Jon sing properly the chorus of In These arms? I mean, not that final parts of "Baaaaabyyyyyy" or "There's nothing I wouldn't dooooooooo", but the chorus, couldn't Jon sing it properly?
Also in I'd die for You.... Its weird listen to the song live nowadays.
Again the chorus... seems strange
Also, Bad Medicine its other example of the chorus sung with a key too low.
Can't Jon do it anymore?

Seeing Jon singing nowadays songs like, Always, I Believe, Dry County, Lie To me, These Days, among others I think he could put more effort in the songs that I especified in the beggining of the thread.
Thoughts?

All sounds fine to me....

The list goes on. The chorus of Prayer or Radio Saved My Life...

Yeah, exactly

But Prayer sounds good.

I don't know a lot about music but from what I've read here a lot of songs are taken down a semitone when played live, but In These Arms was taken down 2 full steps even after that, so it's much lower than it used to be, and lacks power. I'd personally rather them make Always the regular ballad and drop In These Arms now anyway - more people know Always and Jon can still sing it (well, this year he can)

I thought he sounded good during In These Arms.

where has the key change outro gone from prayer, i dont think hes done it this tour.

He did.
Very few times, but he did.

He's always done the first/third lines of the chorus after the key change.

I believe he was talking about that "WHOA" part right after the "you live for the fight... when its all that you've got"
