and work on it now and then, but it never really worked. Finally on this record it seemed to gel". Mellencamp said during his iHeart Radio release party for Sad Clowns & Hillbillies, prior to duetting on the song with Clark: "Bob wrote the song, and it didn't really have a very good arrangement on it.

We knew we didn't want to make a traditional duets record". Mellencamp changed Carter's original line, "I close my eyes and I see you", to, "I see the sun setting on you". Carter later added in a 2019 interview with Glide Magazine: "With 'Indigo Sunset,' he got a co-write on that, largely to do with the fact that he changed the title and the hook line: 'I see the sun setting on you,' and he changed like a
