In the demo version of Jason Isbell's "Elephant," he sings:

 

When she was drunk, she made cancer jokes

Made up her own doctors' notes

Surrounded by her family, I saw that she was dying alone

But I'd sing her Harry Nilsson songs

And she'd get high and sing along

She don't have a voice to sing with now

 

In the version released on his 2013 album Southeastern, he replaces "Harry Nilsson songs" with "classic country songs" in the lyrics.
