 After decades of singing anthemic songs like Livin' on a Prayer, You Give Love a Bad Name, and Wanted Dead or Alive, in sold-out stadiums around the world, Jon Bon Jovi started having vocal problems that got worse over time. He tried every kind of therapy, and when none of them was effective enough to make a significant difference, he did what he wanted to avoid. He had surgery. Although it didn't restore his voice to what it used to be, the surgery made it possible for him to sing again.
