Here is an earlier version of the familiar song - but with no Jimmy to crack corn:

The News (St. Augustine, Fla.)(June 18, 1842):

SONG.--OF THE BLUE-TAIL FLY.

I have sung about the long-tail blue,
So often you want something new,
With your desire I'll now comply,
My song is about a blue tail fly.
       Oh! Do Mr. Bugger
       Oh! Do Mr. Bugger do.

Dar's many kinds of dese are tings,
From different sort of insect springs,
some hatch in June, some in July,
But August brings de blue tail fly.
      

If you should go in summer time,
To Carolina’s sultry clime,
If in the shade you chance to lie,
You will soon find out the blue tail fly.
       Oh! Do Mr. Bugger
       Oh! Do Mr. Bugger do.

When I was young I used to wait,
On Massa's table hand [sic] de plate;
And pass de bottle when he dry,
And brush away de blue tail fly.
       Oh! Do Mr. Bugger
       Oh! Do Mr. Bugger do....

It continues almost identically to the 1846 version I posted on 29 May
20, but with different refrain.

"Mr. Bugger" is the equivalent (one hopes) of "Johnny Booker."

Reminder from an earlier post: the tune usually sung today is essentially the first strain of "Git Up in de Mornin'" (1855):

The tune seems first to have been associated with "The Blue-Tail Fly" in print in Dorothy Scarborough's "On the Trail of Negro Folk Songs" (1925).
