Billy and Mandy
The album, Blown Away, comes out May 1, and it includes a song called "Forever Changed," about a married mom who is dying.
“I get emotional even talking about this song, to be honest. It’s just beautiful,” Carrie said with tears in her eyes.
Carrie says she remembers her grandmother getting confused.
“It just becomes very real. . . . and I remember my grandmother at the end of her life, looking at my dad and thinking that that was my grandfather.”
Concertgoers likely won't ever hear the song performed live.
