You guys need to have a little more faith, give the guy a chance...trust me I'm concerned as much as any of you (probably more) but it's not that easy to sing night after night in amphitheaters and arenas, it takes a toll on any singers voice.
These videos give me hope that he can recover because they're not from that long ago...(Solo show in Delray & a clip from the AFE tour)

He's pretty much spot on, I just think his voice is worn out from rehearsals, recording the new record & of course this tour but I do have hope for the guy that he can recover.
