Exactly.

It's pretty clear that his vocals chords are very fragile at the moment and they don't handle 2+ hours of singing every two days. When this happens, your vocal chords don't recover from the last show like they used to before.

The bad news is ... judging by the way he's straining and his voice is behaving, this is permanent. I think he will have to resort to surgery if he wan't to carry one.

He had some troubles during 2003-2007, but it's nowhere close as this now.
