Bon Jovi
Jon gave everything he had to sing "Livin' on a Prayer" during the first part of the Slippery When Wet tour, and it was seriously damaging his voice. He was barely able to sing at the end of the tour and he had to use a lot of backing tracks to fill out the parts that he could not sing. He also used the services of a vocal coach and some steroids to help him finish the tour without losing his voice completely. At the end of the tour, they had played 206 shows all around the world. The band members took a break before going back into the studio to make another album.
