Rascal Flatts launches its all-band tour Friday (June 15), and the opening acts started to tell ABC News Radio how wild it's gonna get on the road—until they remembered their kids are coming, too.

"I have a feeling it's gonna get a little wild and crazy," Little Big Town's Phillip Sweet says, and his bandmate Jimi Westbrook agreed: "It is gonna be complete debauchery."

Leave it to the Little Big Moms to bring the guys back down to earth.

"The debauchery ends around 10:30 when we have to make sure that our little ones are still down," Jimi's wife/bandmate Karen Fairchild says.

And that won't be easy, she adds.

"In the summertime when the sun goes down later, it's so hard to get the babies [to sleep]," Karen said. "They hear the music and they want to watch all the acts."

Oh well. The Eli Young Band and Edens Edge also are joining the Flatts tour. Nannies not included. . . .
