The Kings of Leon got less than a royal response this weekend after frontman Caleb Followill cut short their Dallas concert Friday night.
About four songs into the 11 they performed, Caleb Followill started complaining about losing his voice. He told the crowd he was feeling ill, saying, “If you guys would please help me sing, I’d love it.” About 50 minutes in, the rocker, 29, said he needed a break. “I’m gonna go backstage for a second and I’m gonna vomit,” he told the audience at the Gexa Energy Pavilion. “I’m gonna drink a beer and I’m gonna come back out and I’m gonna play three more songs.”
