Since the release of Only By the Night in 2008, Kings of Leon have experienced a very successful three years. This summer however, they have not been so lucky. The band ended a show early in Dallas due to lead singer Caleb Followill’s bout with heat exhaustion and vocal issues. After the short-lived performance bassist Jared Followill addressed the audience, blaming Caleb for not returning to the stage and has since stated that the band is dealing with much bigger issues than heat exhaustion. Now, Kings of Leon has officially cancelled the remainder of their 28-date summer tour, including their show set for August 27th at Verizon Wireless Music Center.
