Kacey Musgraves poured a lot of heart and soul into her latest album, Pageant Material.

The critically-praised sophomore album is chockfull of gems like “Dime Store Cowgirl,” “Late to the Party” and, of course, the deliciously cheeky “Biscuits.”

But there’s another track guaranteed to stop you dead in your tracks as you let this masterful project play.

It’s “This Town,” which features a very, very special guest appearance. No, it’s not a big country star or a pop pal. It’s the voice of a woman that will always have Musgraves’ heart -- her late grandmother.

“There’s a really special moment that happens in the beginning of this song that you’ll hear, and it’s a woman’s voice,” Musgraves says. “It’s my Memaw’s, Barbara Taylor. She’s passed away last December. She was the most interesting woman ever.”

The Texas native reveals her beloved grandmother worked as a nurse in the ER and was never at a loss for “insane stories of all these crazy people coming in,” so a few years ago at a family gathering, Musgraves got the idea to record some of these wonderful tales for posterity on her phone. Lo and behold, they provided more than just a great memory. They gave Musgraves some fine material.

“Whenever we were producing ‘This Town,’ I kind of pictured like a radio or like a TV in the background or like small town conversation,” she recalls. “I was going through my voice notes, and I brought that up.”

She then told her co-writer Shane McAnally of the recording of her grandmother’s voice.

“And he said, ‘What if we put that in the song?’ And it was brilliant, so we found a good part of the story and put it in there,” she says.

Now the world gets to experience to magic of Memaw and her incredible stories. And you know she herself would be beaming with pride at every bit of success her granddaughter has earned.

Pageant Material is now available as a special pressing on pink vinyl.
