Brandy Clark has already pushed the boundaries of country music with songs she's written for other artists, including Kacey Musgraves' 'Follow Your Arrow' and the Band Perry's 'Better Dig Two,' but now it seems the singer-songwriter is about to expand her horizons even more.

Clark, along with good friend and fellow tunesmith Shane McAnally, was tapped to write the songs for the upcoming Broadway musical, 'Hee Haw,' and she says nothing is off limits.

"With Broadway, you can push the boundaries, so there's some pretty risque content," Clark tells Rolling Stone Country.

The musical, which takes place in fictitious Kornfield Kounty, includes 19 of the 30 songs that the pair wrote for their Broadway debut. But the Washington native admits that, while she is comfortable penning songs for artists like Keith Urban, Reba McEntire and Miranda Lambert, writing for 'Hee Haw' was an entirely different experience.

"It's one big love story that takes two and a half hours, so you're telling little bits of the story but can't let too much unravel at once," she explains. "For me, songwriting is storytelling, and that is storytelling at its finest."

Steve Buchanan, head of the Opry Entertainment Group (which owns the Grand Ole Opry) and producer of the hit TV show ‘Nashville,' is producing the show, along with the Opry's GM, Sally Williams. Robert Horn, whose credits include the musical '13,' is writing the script for the upcoming musical.

The 'Hee Haw' musical will resurrect many of the same characters in the original variety show, which aired from 1969 to 1971 before spending 20 years in syndication. Unlike the original show, though, the musical will focus on one main storyline, about a “wily sexpot from Kornfield Kounty” who is engaged to be married, but wants to explore the world before settling down.

Clark's debut album as a solo artist, '12 Stories,' was released last year. The songstress wrote or co-wrote all 12 songs on the album, which she says she did with a specific accomplishment in mind.

"My goal as a writer is always to write songs that people who aren’t songwriters would write, if they were songwriters," she tells The Boot. "So I hope that’s what this record will do. I hope that someone who’s in Middle America taking their kids to school, and going and working at a bank or a grocery store, will say, ‘That’s my song.’ That’s what I really hope.”
