Meghan Linsey and Joshua Scott Jones of Steel Magnolia were on cloud nine earlier this week, following their showcase at Los Angeles' The Mint and their first-ever encore performance. After the CMA Vocal Duo of the Year nominees' set, which included everything from Hank Williams and Dwight Yoakam covers to the pair's newest single 'Just By Being You (Halo & Wings) ,' the energy from the crowd merited their return to the stage with Waylon Jennings' 'Lonesome, On'ry and Mean.'

When such a spontaneous moment occurs during a show, do artists have a "just in case" song already prepared? "No!" the couple tells The Boot in unison with a laugh. "That's just a song we usually put in our set that we didn't tonight," Meghan explains. "After the encore, I was mad," says Joshua. "I was complaining, because that wasn't really a duo song. I mean, if you think of a duo doing an encore, they're not going to do a honky-tonk, four-on-the-floor Waylon Jennings song."

"Or maybe now they will, because we did!" interjects Meghan.

That same charm was evident onstage as Meghan and Joshua entertained the crowd with not only their energy-filled acoustic set, but their chemistry and banter.

Before launching into 'Edge of Goodbye' from their upcoming album, Joshua told the crowd, "It's about a nice girl, like Meghan, and a loser guy, not like me [laughs]." Later, Joshua confessed, "I'm feeling honest." "Oh, God," was Meghan's response. Joshua continued, "Let's just say, I came home really late one night and someone had packed up all their stuff and left. Then, someone wouldn't answer their cell phone, so I sat down and wrote this song, 'Without You.'"

Joshua's frankness carried on throughout the night as he addressed the issue of working with your significant other. "People always ask us if it's hard being a couple," he explained to the room. "It's a real motherf---er!" The crowd erupted in laughter and Meghan shot him a look, which prompted Joshua to add, "Nah, it's worth every second."

The pair also made sure to pay musical tribute to their heroes with renditions of Johnny Cash and June Carter Cash's 'Jackson,' Hank Williams' 'I'm So Lonesome I Could Cry' -- which they first performed while on CMT's 'Can You Duet?' and later during their Grand Ole Opry debut -- and Dwight Yoakam's 'Fast As You.'

While their vocals and personalities thrilled the audience, the encore was the highlight of the evening for Steel Magnolia. "It's a dream come true," Joshua tells The Boot. "We are thankful everyday for what we're doing and that it's catching on fire."

Steel Magnolia are currently on Brad Paisley's H20 World Tour, which stops in Boise, Idaho, tonight (September 23).
