Some floating verses show up in bothAfrican American spirituals & secular songs.

The third verse posted above certainly seems like it could be used for a spiritual:

One uh these days, an' it won't be long,
Call my name an' I'll be gone.
Fare thee well, O honey, fare thee well.

I recall reading somewhere-in one of your posts, Q?-that the line "wear my apron high" means that the woman is pregnant.

I'm sure there are other songs with those "apron verses", but I can't think of any right now.
