Even amid personal heartbreak, Miranda Lambert is still able to get out there and give fans a performance they won’t forget. At a show in Nashville July 28 at one of Music City’s top venues, 3rd and Lindsley, the artist performed her song “Another Sunday in the South” for the first time as part of an intimate unplugged set benefiting her new scholarship fund for women pursuing careers in the music industry.

“We love ’90s country so much, and we miss it,” Lambert explained to the excited crowd before performing the fun track. “We wrote this, and we tried to fit as many country titles as we could … If you don’t think it’s cool, don’t tell us because we think it’s cool.”

The audience sang along to the laid-back, nostalgic tune as Lambert and her bandmate strummed acoustics and harmonized beautifully.

Lambert wrote the tune with Jessi Alexander and Ashley Monroe for her most recent record, Platinum, placed carefully as the last track on the album. It references the '90s country hit “Sunday in the South” by Shenandoah, whose vocalist, Marty Raybon, actually appears on Lambert’s recording.

“I hear the track, which Miranda had already put her vocal on, and for the first time, I thought they were serious,” Raybon tells Billboard. “I called him back and said, ‘This is really cool. Is this really going on Miranda’s record?’ He said it was, and I asked him what he wanted me to do. So I came up to Nashville, and we played with it.

“To be honest with you, I sat there totally in amazement that I was part of it,” he recalls. “I don’t want to use the word surreal because I think it’s become a buzzword that has gotten to be way overused. But there really was a sense that it wasn’t really happening. Then I get a copy of it mixed down, and I thought it was killer.”

Lambert also joined forces with Little Big Town singer Karen Fairchild to close the show with "Girl Crush." See that performance below.

Lambert’s scholarship fund, called the Miranda Lambert Women Creators Fund, will provide more than $40,000 to a female student attending Nashville’s Belmont University majoring in songwriting, entertainment industry studies or music business. Its first scholarship will be applied to the 2016-2017 school year. Lambert is gearing up for her Roadside Bars and Pink Guitars tour, on which she will bring RaeLynn, Monroe, Clare Dunn and Courtney Cole.
