The first two are verses refering to "Golden Slippers" (See: "Oh, Dem Golden Slippers" by James A. "Jimmy" Bland) the interpretation is fairly easy to understand:

Oh, my golden slippers am laid away
Kase I don't 'spect to wear 'em till my weddin' day,
And my long-tailed coat, dat I loved so well,
I will wear up in de chariot in de morn;
And my long white robe dat I bought last June,
I'm gwine to git changed Kase it fits too soon,
And de old grey hoss dat I used to drive,
I will hitch him to the chariot in de morn.

Chorus: Oh, dem golden slippers! Oh, dem golden slippers!
Golden slippers dat I'm gwine to wear be-case they look so neat;
Oh, dem golden slippers! Oh, dem golden slippers!
Golden slippers I'm gwine to wear to walk de golden street.

The last two are floating verses from other songs. If you want some of the songs they floated from I can give them to you.

Since the last two verse are filler verses, they don't add much in terms of plot or cohesion. Maybe someone can add meaning but I don't think there much intended.
