One of the most heartbreaking love songs ever. She is saying goodbye "here in the dark in these final hours" to someone she loves; someone who didn't return her love. She is honestly accepting a heartbreak and a goodbye, honestly accepting the pain, trading everything--even her dignity--for one last night.
If you understand this song, you probably won't be able to hear it without crying.
Bonnie Raitt performed this song in a concert to say goodbye to Don Kirschner when he died. She's got courage.
