Tim McGraw and Faith Hill get caught up in the emotion of his new song 'I Called Mama'

If your emotions get the best of you the first time you hear Tim McGraw's new song, "I Called Mama," rest assured, you're not alone. The same thing happened to the superstar himself the first time he heard it.

"When it got to the hook of the song, I just sort of fell apart," McGraw recently told reporters during a virtual roundtable. "And then I wanted [my wife] Faith [Hill] to hear it, but ... was just a guitar demo, or a guitar work tape."

"I didn't want Faith to hear it [like that]," he explained. "I wanted to sing it to her. So I was trying to learn the words to it really quickly, until I could sing her, you know, just the first verse and a chorus."

But learning "I Called Mama" only seemed to intensify its emotional impact. "In about 30 minutes, I had it ready," McGraw remembered, "and I said, 'I want you to hear this song.'"

"So I sat down at the kitchen table, and I started singing it," he continued. "And I couldn't get through it ... every time I tried to get to the chorus of it, I would fall apart ... and she would start crying because I was crying."

"But it really hit me," McGraw said. "It has a simple message to it, but it just means so much."
