Not only on just this song, but in general, it seems to me that Jon is focusing so much on trying to sing the notes that he just isn't capable of focusing on anything else. Not his timing, the overall feel of the song, his performance delivery...nothing but trying to sing the proper notes. He's even given up playing his acoustic on this song and Wanted, which I'm guessing is because that would now be too much of a distraction for him too.

It's sad to see what used to be so effortless for him has now become a huge, monumental task. Eyes closed with a death grip on the mic seems to be what he feels he has to do now to get through most songs. He can't be enjoying performing like this.
