Kings of Leon were on Carson Daly's show last night in a lengthy interview segment where Daly (who makes sure everyone knows he likes them) talks to Caleb and Nathan Followill about the Grammys (they won Best Rock Performance By A Duo Or Group With Vocals), how they're starting to get noticed in the U.S., and how it would feel to be the biggest rock group in the world. I have to agree with Caleb when he says he never expected "Sex On Fire" to win a Grammy. To watch the interview, go here.
