In an interview with Performing Songwriter magazine, Colvin described how she co-wrote songs for Fat City:[6]
The way that I generally co-write is that someone else writes the music or part of the music. Like on "Round of Blues" I wrote the whole song but Larry Klein said that it needed a bridge. So he wrote the bridge and I wrote the words to it. But Elly and I really shared every part of ["Set the Prairie on Fire"] equally. She wrote some of the words, I wrote some of the words, she wrote some of the music, I wrote some of the music.
