Jon Bon Jovi is a LEGEND. That's all that needs to be said. From his music, to his giving ways, he just a damn good person it would seem. HOWEVER, what is happening to him on this tour needs to be dealt with.
In the videos you'll see below he is struggling mightily and it should NOT be getting top dollar per ticket at this time. Is it poor breathing technique? Is he suffering a serious hearing problem which is causing him to sing grossly out of tune & key. OR is he just trying to sing these songs in a lower key. If so, it does not work.
Yes these songs and his vocal over the year would be like a salad shredder on your vocal chords but WOW.
Watch the "Wanted Dead Or Alive" video and notice his mouth. It's almost like he's having issues with his motor skills. I'm not here to make fun, I am worried for the man.
