Kings Of Leon abandoned a gig in Dallas last night (July 29) after an apparently drunk Caleb Followill stormed offstage in search of another beer - scroll down and click below to see fan footage of the palaver.
After the band played 'Notion', the eleventh song of their set at the Gexa Energy Pavilion, the singer headed backstage complaining of vocal problems.
He told fans he was going to vomit and grab another beer, promising to return for three more songs which ultimately failed to materialise.
Caleb commented:
I'm trying my best to sing but I haven't got a voice, I’ve got nothing here. I'm not drunk, I'm just fucking hot

However, after Caleb was a no-show, bassist Jared Followill came out to apologise to the jeering crowd, stating his brother was "a little unfit" to carry on with the gig.
Jared stormed:
Fucking hate Caleb, not us. I don't know what to say. It's not our fault. It's Caleb. He can't play the rest of the show. We will be back as soon as possible

Jared added: "I know you guys hate us. I'm so sorry, fucking burn our records. We would play right now if we could. We're so sorry."

Commenting on his Twitter page after the gig, Jared repeated his apology and said that the band had "internal sickness and problems that need to be addressed".

It's not the first time Kings Of Leon have abandoned a gig in recent times - last year the band stormed offstage in St Louis, Missouri after being hit by pigeon droppings.
