Jon's voice has been getting worse since the Crush tour which was way worse than These Days. Nowadays he seems to have trouble even singing in tune.

He had problems with his voice during the SWW tour but recovered and NJ-TD period was the best. KTF - Evening with BJ shows how powerful his voice was. Simply amazing, Bon Jovi at its best. Live from London was awesome too, very relaxed. Zurich was nothing to write home about and all the later performances seem to be getting worse and worse. Things looked a bit better for the 2001 OWN tour but it seems it was just one last spark. His voice on Bounce tour sucked big time. TLFR was different since there was very little using of higher tunes. Whenever there was a chance to show off his voice, he sang lower than he should have. The last webcast was just dreadful.

I trully hope his voice recovers again. It would be nice to see a show again where he would be relaxed and wouldn't struggle so much just to be in tune. The rest of the guys are still great. Richie could do a bit more solos, acoustic intros like he used to.

If Jon's voice continues to deteriorate in this pace, he won't be able to perform much longer.
