That CMA Music Festival show on TV on Wednesday night (Sept. 1) was three hours long, so some of the little moments might have gotten lost in the shuffle. And I'm here to pull a couple out and shine a light on them because to me, they said a lot about what motivated the genre's biggest stars to head down this path in the first place. At Taylor Swift's 14-hour autographapalooza, she said, "I remember when I was a little kid, I used to see Shania Twain and I just remember thinking if I ever got a chance, by some crazy streak of luck, to be on a stage, I'd want to do as much as I could to say thank you." Dolly Parton was the one who did it for Rascal Flatts' Jay DeMarcus. "I was at the Ohio State Fair when I was probably 8 years old watching Dolly Parton," he said. "There was a switch that flipped inside of me, that I knew that's what I wanted to do for the rest of my life."
