The version in Lomax (American Ballads and Folk Songs)is very similar to the one in the Silverman book. Lomax has the additional stanzas

2. Better git yo' overcoat ready
Well, it's comin' up a norther.

6. (after "almos' flyin'")
One o' dese mornin's, an' it won't be long,
You gonna call me an' I'll be gone.

9. (after "ninety-nine years" stanza)
I b'lieve I'll go to de Brazis line,
Ef I leave you here, gonna think I's flyin'

16. (after "some goin' home")
I looked at my Ol' Hannah, and she's turnin' red,
I looked at my podner an' he's almos' dead.

18. (after "drop dead")
Well, I wonder what's de matter, somepin' mus' be wrong
We're still here rollin', Shorty George done gone.

Maybe I should have assembled it all in one post.^^
