Kings Of Leon stars Nathan and Caleb Followill realised they were destined to become rock stars after sneaking into a karaoke bar as teenagers and performing Wild Cherry's Play That Funky Music.

The siblings couldn't believe their luck when their rendition of the song took the audience by storm - and won them a clutch of female fans.

Caleb tells Entertainment Weekly magazine, "It was my 18th birthday, on Bourbon Street (in New Orleans, Louisiana)... and that was actually the first time I ever got onstage and sang.

"A woman flashed us and we looked at each other and were like, 'All right, I guess this is what we're gonna do forever'."
