Rock bank "Kings of Leon" cut short their show in Dallas’ Gexa Energy Pavillion Friday night due to the heat. It is reported that their lead singer Caleb Followill left the stage abruptly halfway through the performance, shocking his band-mates and fans both. He said he was feeling too hot to sing.

Temperatures in the city had reached in the 90s. According to a Houston news report, Caleb suffered from heat exhaustion and dehydration during the show, which caused his vocal chords to seize.

"My voice is completely 100 percent wrong, I'm sorry," the 29-year-old singer said to the crowd. "I'm about to fall down here because I'm so goddamn hot…I'm gonna go backstage for a second. I'm gonna vomit, I'm gonna drink a beer and I'm gonna come back out here and I'm gonna play three more songs."

Caleb did not come back. The band did not seem to be happy with the way things went. Guitarist Jared Followill, Caleb’s younger brother told fans ,"We are so unbelievably sorry—there's no words right now".

"Caleb's just maybe a little unfit to play the rest of the show. I know you guys f--king hate us...It's really not our fault. We will be back as soon as possible...F--king hate Caleb, not us," he added.

Jared took to the twitter to again apologize saying, "I love our fans so much. I know you guys aren't stupid. I can't lie. There are problems in our band bigger than not drinking enough Gatorade."

Jared’s twitter seems to be hinting at internal problems.

The cancelled show has been rescheduled for September 22, the band’s representative confirmed.

The "Sex on Fire" rockers also postponed a concert scheduled for Saturday outside Houston. These live problems arrive a year after the band abandoned a concert in St. Louis three songs into their performance because pigeons were defecating on them.

The family rock band came together in 1999. Brothers Ivan, Caleb, Jared and cousin Matthew are part of the group. The band found initial success in the United Kingdom. They became popular in the United States in 2008 with the release of their fourth album, Only By The Night.
