Dr. John, Dr. John Plays Mac Rebennack, 1981 on Clean Cuts.

Dr. John used “Mac Rebennack” for his writing credits (or Mac Rebennack used Dr. John for some of his performing credits, if you prefer). Either way, this is Malcolm John Rebennack Jr. On solo piano.

And no, he was not a medical doctor. Neither am I, though I do have a PhD and people have called me Dr. John.
