Expert: Bruce Springsteen, Jon Bon Jovi, and Steven Tyler overcome obstacles to demonstrate that “music is their lives.”

Although rock stars are devoted to their fans, there are instances when this devotion pushes them too far and negatively affects their health. Due to serious health concerns, a number of well-known acts have had to postpone their tours in the past year.

This week marks Bruce Springsteen’s comeback to the stage following a peptic ulcer last year.

The tour began on March 19 in Phoenix. The “Born in the USA” singer reportedly said to the audience, “Phoenix, first, I want to apologize if there was any discomfort because we had to move the show last time,” according to the Associated Press. I hope we didn’t cause you too much trouble.”

He performed for almost three hours, using his voice, dancing, and even pulling off his shirt.
