Darius Rucker and Charles Kelley of Lady Antebellum wrote Rucker's recent single "Homegrown Honey" together, but the co-write almost didn't happen because Rucker was close to backing out.

"We were playing golf one day, and he said, 'Dude, we've never written a song together.' So we set a date and went and did it," Rucker tells Rolling Stone Country. "The great thing for me about writing with him is, he's got that voice that's like mine. But he'd sing a part I would never sing."

However, Kelley notes that on the day of their songwriting date, Rucker almost bailed.

"He said, 'I don't know if I can write tonight; I'm fried.' I said, 'You're not backing out!'" Kelley laughs. "It worked out, and after we wrote it, he said, 'This is my first single, I just know it.'"

Not only was it Rucker's first single from Southern Style, "Homegrown Honey" was different than anything he'd written previously. Rucker admits that the song brings out "a cool side of fun for me," which is exactly the goal that Kelley had in mind.

"I told him, 'You're known for a lot of serious stuff, like [Lady Antebellum], but you also need some fun, light-hearted [songs] to play," Kelley explains.

While "Homegrown Heavy" isn't the deepest, most intentional song, it wasn't meant to be.

"It wasn't meant to change the world," Rucker says. "It was meant for people to enjoy it."

For his part, Rucker is eager to explore new musical territory with Kelley again soon.

"I'd work with Charles Kelley anytime," he says. "I'd go do a Pancho and Lefty record with Charles. He is class, man."

Rucker is currently touring in support of Southern Style with Brett Eldredge, the Brothers Osborne and A Thousand Horses. The tour was recently extended into November; David Nail will begin opening for Rucker in October.
