Garth Brooks gave his Nashville fans something to talk about on Wednesday night (Feb. 25), when he played an intimate secret show at Marathon Music Works, treating the audience to a 12-song set and a whole lot of memories.

Music industry executives and radio programmers were in the audience, as well as lucky fans who found out about the show via a local radio station, totaling at approximately 1,000 attendees. The concert was hosted by radio personality Bobby Bones and lasted for over an hour -- and for the fans, it was 60-something minutes of pure bliss.

"We don't have a clue what we're doing," the singer said (quote via USA Today), noting that the show was "a taste" of his current World Tour. "The only thing we know is to have fun -- that's all we know to do."

In a sense, the concert was Brooks going back to his roots -- and to the place he feels most comfortable.

"I would have never left the clubs, ever, if there wasn't more people outside than inside," he told USA Today after the show. "Arenas, stadiums -- I'm lucky enough to be called an entertainer in those, but this is my forte. I love clubs; this is what I grew up on."

Brooks announced his touring comeback in December of 2013 as a surprise on Good Morning America, admitting that it felt good to throw his hat back into the ring. Although he hasn't toured in years, Brooks did play some shows in Las Vegas and perform a few shows after Nashville's flood in 2010. The "Friends in Low Places" hitmaker says that he based his World Tour off of same structure as the latter shows.

"The flood shows, that was nine shows -- out of shape, hadn't been doing it. I remember coming out going, 'I'm just not going to make it, I need your help,'" he says. "Now, every city I roll into, I make sure to tell them, 'Hey, guys, I'm 150 years old, I need the help.' It's worked out great."

Brooks began his secret Nashville set with a new song, "Cold Like That," but he made sure to intersperse hit songs like "Papa Loved Mama," "Two Pina Coladas," "The Dance" and "The Thunder Rolls" into the set. He closed out the evening with his inspirational 1993 hit "Standing Outside the Fire."

The singer's wife, Trisha Yearwood, was also an attendee at the show and posted a hilarious photo of herself on Instagram. In the picture, she's holding two plastic beer cups with the letter "G" on them (for Garth) up against her chest, and she captioned it "Here at Marathon MusicWorks watching G with my double g's! #goinghomewithhim."

In addition to going home with her hubby after the show, Yearwood will be heading back out on the road with him as his tour continues, including just-announced dates in Portland, Ore. A complete list of Brooks and Yearwood's World Tour tour dates is available here.
