Glen Campbell's daughter Ashley is releasing her debut single, "Remembering," in honor of her father and his ongoing battle with Alzheimer's disease.

With lines like, "Bone for bone, we are the same / Bones get tired, and they can't carry all the weight / We can talk until you can't even remember my name / Daddy, don't you worry / I'll do the remembering / Daddy, don't you worry / I'll do the remembering," the song is a poignant tribute to her father, whose memory is quickly vanishing.

"I wrote it with my good friend, Kai Welch," Ashley Campbell tells Rolling Stone Country of "Remembering." "I came up with the idea and the melody when I was living with my mom and dad in Malibu a couple of years ago. I wanted to write something that expressed to my dad how much I wanted him to feel safe ... that he didn't have to worry; I'll take care of him when he can't take care of himself.

"When you're little, your parents take care of you and make the world not such a scary place. As you get older, those relationships change and kind of swap places," she adds. "The kids are the ones taking care of the parents and making sure the world's not a scary place for them."

Campbell, as well as her brothers Shannon and Cal, performed with her famous father on his Goodbye Tour, following his 2011 diagnosis with Alzheimer's.

"I can't even put it into words how priceless it was for me to be able to perform with my dad," Campbell tells "It was a ridiculously valuable experience for me as a performer. But, more importantly, it was so great to watch my dad doing what he loves. Being able to witness the legacy he created and to see all of the fans who love and support him — being caught in that crossfire of encouragement was amazing."

"Remembering" will be officially released on June 29 on Dot Records, after the award-winning documentary Glen Campbell: I'll Be Me, about the country legend's life, career struggle with Alzheimer's, airs on June 28 at 9PM ET on CNN. A different version of "Remembering" is available on documentary's soundtrack.

Ashley Campbell is currently in the studio with Julian Raymond, who co-wrote her father's final song, "I'm Not Gonna Miss You," working on her own album.
