"Sangaree" is a poem by Langston Hughes, and also a bluegrass piece, a song by Dunbar that has a line about sipping sangaree (sangria), and I think other songs, but they have nothing to do with "Ja-Da."

Paul Laurence Dunbar (African-American poet):
Verse in "Opportunity," 1901

Lemon pie an' ginger-cake,
Let me set an' think-
Vinegar an' sugar, too,
That'll make a drink,
Ef they's one thing that I loves
Mos' pu'ticlahy,
It is eatin' sweet things an'
A-drinkin' Sangaree.
