'The Dance' is a special moment during any Garth Brooks show -- but something truly incredible happened during the song at one of Brooks' Minneapolis, Minn., concerts on Friday night (Nov. 7).

Teresa Shaw, who is battling cancer, came from Osage, Iowa, with her 19-year-old daughter to see Brooks' concert, bringing with her a sign that read "Chemo this morning. Garth tonight. Enjoying the dance." The Des Moines Register reports that Shaw has been battling Stage III breast cancer since June.

Arena staff took notice, showing Shaw and her sign on the video screens above Brooks' stage during the song, eliciting cheers from the crowd. And then, it got even cooler.

"The next thing I knew, another usher was coming up to me and were like, 'Follow us,'" Shaw tells the Register. "And they took me to the very front, right in front of him."

Brooks spotted Shaw and walked over to where she was standing, continuing to sing the song in front of her. Then, the country legend sat down on the stage, gave Shaw his guitar and a kiss on the forehead (and a fist bump!), and took her sign on stage with him.

"I'm one of those guys that says, 'Man, if God would just give a big old hand that comes down from the sky and write 'I exist,' then there would never be any doubt,' right?" Brooks said to the crowd, still holding Shaw's sign. "Well, I want to tell you, right now, God just stuck his hand out, and he wrote.

"You have all of my strength, you have everybody's strength in here," he continued, speaking to Shaw and drawing a huge response from the audience, "and you go kick cancer's ass!"

Shaw says it's an experience she'll never forget.

"I was just hoping he would see [the sign] and maybe if I could get him to get it signed," she says. "To give away something like [his guitar] is just remarkable, and now if I ever have a bad day, I can always go look at his guitar and get inspiration."
