Refreshingly different for you and, I think, one of your best. You sang with a lot of emotion. Reminds me a bit of St. James Infirmary, just a bit. Great job!!
I think that it is your best to date! I also thought of St James Infirmary.
Although it didn't distract from the song I would have preferred a more sad blues instrumental part in play of the sax. Either a wailing sax or guitar would be better, but again that is only me and others may disagree.
Regardless this is excellent - loved it.
