The Kings of Leon tour had been cancelled for the rest of their US dates after lead singer Caleb Followill abruptly left the stage during a concert claiming he was ill. The band still had more than 20 dates scheduled on the Kings of Leon tour.

At a Kings of Leon concert in Dallas on Friday, lead singer Caleb Followill told the audience “my voice is 100-percent wrong.” He said he was “about to fall down here because I’m so goddamn hot” and said he was going backstage to “vomit” and “drink a beer.” Followill never returned to the stage, despite having promised he would come back to play more songs.

When Followill did not come back out, the rest of the band apologized to the crowd while some fans booed them.

Jared Followill, Caleb’s brother and back-up singer, followed up about the incident on Twitter. “There are problems in our band bigger than not drinking enough Gatorade,” he posted.

On Monday, the band announced the rest of their US tour would be cancelled due to Caleb Followill’s “vocal issues and exhaustion.” In a press statement, the band members said they were “devestated” “but in order to give their fans the shows they deserve, they need to take this break.”

Due to the band’s upcoming international tour in the fall, the Kings of Leon tour in the US will not be rescheduled. Ticket holders have been promised full refunds instead.

Jared Followill posted on Twitter that he was “utterly depressed” about the tour cancellation. “It’s completely out of my hands. Family has to come 1st. If bass solos & backing vocals were more popular, I’d be there.”

Nathan Followill, the band’s drummer and older brother of Jared & Caleb, also took to Twitter to express his sadness over the tour being cancelled. “Bummed about the tour not happening,” he posted. “So sorry 4 all the fans. We just need some rest. Thanks 4 understanding. WE ARE NOT BREAKING UP!”
