This is one of my favorite melodies of all-time, ever, in the history of all of the music I have heard in my 44 years, soon to be 45 years. I first heard this when I came across Nina Simone playing this. What a powerful performance!!
I have made two arrangements of this melody. The one posted above I consider to be a more advanced arrangement. You can find the score/tab here. The other arrangement is an “easy arrangement.” That can be found in my first volume of easy arrangements.
