I caught this song during my second year at college when I was preparing for a story telling competition back in 2008. There I realized how great she was at conveying lyrics through music. She's not singing I tell you, she's telling you a story. Wonderfull voice...
You simply cannot sing this song self-consciously and expect to compare favorably with its Nancy Wilson's renditions. You must sing it to the husband. Period. And you have to have some idea about the blues.
