The Band Perry light up the TODAY plaza with hits, raucous energy

Friday's a pretty energetic day around TODAY already — c'mon, it's almost the weekend! — but bring The Band Perry onto the plaza to play a handful of their rollicking tunes, and the level ratchets up another notch. 

Singer Kimberly Perry and brothers Neil Perry and Reid Perry popped up on the show to perform their hits "Done," "If I Die Young," "Don't Let Me Be Lonely" and "You Lie," but midway through that set they had a quick chat with TODAY's Carson Daly and Savannah Guthrie to talk about the family biz.

It's nice touring with her brothers, says Kimberly, but even their parents are involved, mostly as "Starbucks runners," she said. Their father was the "original bus driver" for the band, a job he'd like back. "He wants to quit his day job and go on the road," she laughed.

And if you want to know the secret to their apparently boundless energy? Lots of chocolate and no sleep: As Guthrie noted, the band pulled into TODAY around 3 a.m. directly from their last show in Hershey, Penn. "We just didn't go to bed," said Kimberly. "We're all hopped up on chocolate."

With that, take it away, Perry!
