Here are half a dozen doctors for you. Most good, one bad, and one a worm. A personal highlight is "Dr. Thomas Chauke", an excellent tribute from one Tsonga music master to another, but they are all worth a listen. I even remembered to include the Mandaory Reggae Physician for you.
My sister Kate is a doctor and a general all round marvel, so this one is dedicated to her.
