This may be the earliest appearance of a song called "The Blue Tail'd Fly" - the familiar one, presumably:

Daily Republican Banner (Nashville) (Nov. 20, 1838), p. 3:

“On Tuesday Evening, Nov. 20 / will be presented / Mr. M. G. Lewis’ celebrated tragedy in 5 acts, entitled

                                         ADELGITHA
                            Or, The Fruits of a Single Error
                                                      -----------------------
Song, The Blue Tail’d Fly…….by Master Austin.”

The next mention is more than seven years later, from the Daily National Republic (Buffalo, N.Y.) (Feb. 6, 1846), p. 2:

“George J----, the pride of the Podunk bar, can…sing ‘The Blue tail fly.’”

And the earliest text, from the same source and page:

I’ve sung about my long tail blue,
So often you want something new,
With your desire I'll now comply;
My song is about dat blue tail fly.
Oh, Jim Crack Corn don't care,
Oh, Jim Crack Corn don't care,
Oh, Jim Crack Corn don't care.
Ole massa gone from home.

Dar’s many a kind ob dese here tings,
From different sort ob insects springs,
Some hatch in spring and some in July,
But August brings dat blue tail fly.
    Oh, Jim Crack Corn don't care, &c.

If you should go in de summer time,
To Carolina’s sultry clime,
If in de shade you chance to lie,
You’ll soon find out dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

When I was young I used to wait,
On massa table and hand de plate;
And pass de bottle when he dry,
And brush away dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Arter dinner massa sleep,
He make dis nigga wigil keep,
And when he go to shut his eye,
He tell me watch dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Ole massa ride in de arter noon,
I follow wid de hickory broom;
De poney [sic] being berry shy,
When bitten by dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Ole massa ride around de farm,
De flies so numerous did swarm,
One bit de pony on de thigh,
De debil take dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

De pony run, he jump, he pitch,
He tumbled massa in de ditch;
He was dead and de jury wondered why,
De verdict was de Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Dey laid him beneath the simmon tree;
His epitaph is dere, to see,
Beneath dis stone inforced to lie,
All by de means ob de Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Ole massa's dead, oh let him rest,
Dey say all tings are for de best,
I nebber shall forget until I die,
Ole massa and dat Blue tail Fly.
Oh, Jim Crack Corn don't care, &c.

Quite the same text, ”Blue Tail Fly,” except for some additional dialect spellings, appears in The (Charleston, S.C.) Courier (July 19, 1853), p. 4, but there the “Jim Crack Corn” refrain is replaced by “Oh. Mr. Booker, do Mr. Booker, wake up Katy,/ Or I’ll scratch you with a briar.”
