The sacrifice of a chicken, rooster or goat is a central aspect of Vodou religions. The song is about a visit from the Goddess: unadorned.

And I got to thinking about Goddess songs: Poor Rosy, Mary Don't You Weep, Fleur-de-Lis, Mother, I Climbed. Louis came in today and mentioned 'She'll Be Comin' Round the Mountain."
    A central part of Vodou ritual is the sacrifice of a goat, chicken or rooster. These lyrics are from Carl Sandburg's American Songbag:

right under our noses - the Goddess

She'll be Coming Round the Mountain
She'll be coming 'round the mountain when she comes
(when she comes)
She'll be coming 'round the mountain when she comes
(when she comes)
She'll be coming 'round the mountain
Coming 'round the mountain
Coming 'round the mountain when she comes
(when she comes)

Chorus
Singing aye aye yipee yippee aye
Aye aye yippee yippe aye
Singing aye aye yippee
Aye aye yippie
Aye aye yippie yippie aye


Oh we'll all come out to meet her when she comes, etc.

We will kill the old red rooster when she comes, etc.

We'll be havin' chicken and dumplings when she comes, etc.

We'll all be shoutin' "Halleluja" when she comes, etc.
(Chorus)
