Best female jazz vocalist song /disc live setting

I am looking for the one song by a female jazz vocalist in a live setting that you would take with you to audition a system. I am interested in both ballads and swing. I have one I especially like by Ella Fitzgerald "It Don't Mean A Thing (If It Ain't Got That Swing)" on the three cd collection "First Lady Of Song". I have always liked the live jazz recordings with the energy between the vocalist, the band and the audience. I own a multi-disc player with no phono. Please keep that in mind when giving me ideas. Whatever input you can give me would be helpful.
