The song was the first song written by Hiatt following his sobriety from drugs and alcohol which had already contributed to his marriage breakdown and his being released by former record labels.
The original attempt at recording the song took place at a friend's studio and included a larger instrument accompaniment however the recording was plagued by technical issues. The morning after, Hiatt waas informed that his estranged wife had committed suicide. Hiatt attributes the technical problems with the original recording as a sign that the song was not meant to be heard that way and he eventually released the song much more simply with a piano accompaniment.
