Caleb Followill tells all the girls trying to sneak backstage to simmer down.

Monday night’s triple bill at DAR Constitution Hall had something for everyone, assuming they liked their guitars loud and their venues cavernous. Headliners Kings of Leon, touring behind their latest release, the stadium-rock ready Only by the Night, whipped fans into a prolonged frenzy by playing it cool, while openers We Are Scientists and The Whigs had to put in some extra work to win over the late-arriving crowd.

KoL lead singer Caleb Followill seemed a bit sleepy during the start of his band’s set. He kept rubbing his eyes like he was trying to keep them open. Finally a roadie came out between songs and handed him a shot of liquor in a Solo cup. Said roadie waited dutifully for Followill to consume the alcohol before handing over the Gatorade chaser. I guess it’s good to be the King.
