I'm surprised no-one has yet mentioned the Fats Waller/Harry Brooks/Andy Razaf composition, Black and Blue. Here it is with a couple of verses you don't hear that often.

Out in the street, shufflin' feet
Couples passin' two by two
While here am I, left high and dry
Black, and 'cause I'm black I'm blue

Browns and yellers, all have fellers
Gentlemen prefer them light
Wish I could fade, can't make the grade
Nothing but dark days in sight

Cold, empty bed, springs hard as lead
Pains in my head, feel like old Ned
What did I do to be so black and blue?

No joys for me, no company
Even the mouse ran from my house
All my life through I've been so black and blue

I'm white inside, it don't help my case
'Cause I can't hide, what is on my face, oh!

I'm so forlorn, life's just a thorn
My heart is torn, why was I born?
What did I do to be so black and blue?

'Cause you're black, folks think you lack
They laugh at you, and scorn you too
What did I do to be so black and blue?

When you are near, they laugh and sneer
Set you aside and you're denied
What did I do to be so black and blue?

How sad I am, each day I feel worse
My mark of Ham seems to be a curse, oh

How will it end? ain't got a friend
My only sin is my skin
What did I do to be so black and blue?
