Kings Of Leon Reschedule Show After Caleb Followill's 'Heat Exhaustion'

Announcement came after Friday show was cut short when Followill abruptly left the stage.

The Kings of Leon were forced to bring a Friday-night show in Dallas to an abrupt end after frontman Caleb Followill complained of voice problems and then told the crowd at the Gexa Energy Pavilion, "I'm gonna go backstage and I'm gonna vomit. I'm gonna drink a beer and I'm gonna come back out and play three more songs."

Followill then left the stage and never returned, leading his bandmates to apologize to the crowd, saying, "Caleb's just a little unfit to play the rest of the show. ... It's really not our fault, it's Caleb."

Immediately following the incident, KOL bassist Jared Followill took to his Twitter account to further apologize and hinted at a growing strife within the band, writing, "There are internal sicknesses & problems that have needed to be addressed ... I can't lie. There are problems in our band bigger than not drinking enough Gatorade."

In YouTube footage of the Friday show, Caleb Followill is seen engaging the crowd in several lengthy diatribes, urging them to help him sing the words because his voice was "100 percent gone," and adding, "I'm gonna drink some beer and I'm gonna drink some tequila and I'm gonna have a f---ing good time." He also made repeated references to the heat, saying, "Just for the record, I'm not drunk, I'm just f---ing hot. ... I'm about to fall down over here, because I'm so daggum hot."

In the aftermath of the Dallas show, the band announced they were postponing a Saturday concert at the Cynthia Woods Mitchell Pavilion in Houston, claiming that Followill was suffering from "heat exhaustion and dehydration ... [which caused] his vocal chords to seize."

The Houston show was rescheduled for September 22, and the band said they would return to Dallas on September 21 and that all tickets from the aborted show would be honored.

"Kings of Leon apologize to their fans for any inconvenience this may have caused and look forward to seeing their fans again in September," the statement concluded.

There's no word on whether the band's Tuesday show in Tampa would go on as scheduled. A spokesperson for the band did not have any additional comment when contacted by MTV News.
