CAM performed her song "Diane" on yesterday's "Good Morning America" and the song is a response to Dolly Parton's classic "Jolene", so they played a clip of Dolly giving her a surprise message.
Dolly said, "You did good on that. I wish I could be there in person, but I'll be watching you on TV."
The Dolly clip is at 0:50. The song starts at 1:29.
