Rascal Flatts' Jay DeMarcus and his wife, CMT host Allison DeMarcus, recently sat down with veteran Nashville radio personality Gerry House. And while they did discuss the band's new single "Rewind," other things came up along the way.

Things like golf. And diapers. And who is the better cook in the family.

First, House asks them to answer for each other. So Jay (as Allison) says he prefers picking out knickknacks over golfing. Then Allison (as Jay) says she's never changed any diapers.

"I actually just asked my wife the other day -- our oldest daughter is 3 -- and I asked her where the diapers were, if that tells you anything," she said while portraying her husband.

The interview takes place in the home studio of the DeMarcus' house. And eventually, the conversation turned to the band's music and "Rewind," which marks DeMarcus' debut as a Rascal Flatts producer.

"He doesn't want to hear what I have to say about all that," his wife said about keeping her opinions to herself when it came to the band's latest record. "There's no need for me to Yoko Ono the situation since it pays our bills. But Jay's worked really hard, and he's produced so many other people, that this is a really big deal for him to be able to produce something on his own band. There was clearly an extensive application process since it only took 13 years."

Jay explained how he and bandmates Gary LeVox and Joe Don Rooney made the decision for the new album.

"I sat down and said, 'Look, I love this band more than anything. We can go in with the three of us, and I feel like really create some magic together,'" he recalled. "Now with that being said, all of us were working on it very diligently. We did it here at my studio. It was fun for me to sort of have the reins for a little bit. It was a neat thing. Really great for me."

But when the talk turns to the state of country music in general and the music being made by other artists, Jay gracefully tap dances around the question.

"Do you have anybody you would like to wage a jihad against in the country music industry," House asks.

"Gerry, I'm a lover. I get along with everybody. Are there people's music that I don't like? Sure, there are," DeMarcus admits but without naming any names.

House is hysterically funny, and that comes through loud, clear and candid in his new book Country Music Broke My Brain: A Behind-the-Microphone Peek at Nashville's Famous and Fabulous Stars, due out March 4.
