Here's my late-night in the kitchen version of a lovely tune from way back when. It was very popular when it came out and was recorded by lots of cool and interesting people. And this is me doing it.
I play it in Eb - if you want to play along, you can find the lead sheet with chords & melody here
The first version I ever heard was Annette Hanshaw and that's the Gold Standard for me, it's what I hear in my head when I'm singing it for you (even if my voice is a little more growly).
