Waits wrote this song about his new wife, Kathleen Brennan. He was getting over a turbulent relationship with Rickie Lee Jones
when she came into his life and "saved him."
When Jones and Waits split, Francis Ford Coppola asked them both to work on the music for his film One From The Heart
. Jones declined, but Waits took the gig, which is where he met Brennan, who was on the project as a script supervisor. They got married just months later.
