I've been listening to sound samples, and came up with these transcriptions. Because they all come from short excerpts, I don't know if I got all the verses, or if the verses are in the right order.

RAGTIME MILLIONAIRE - William Moore, 1928

CHORUS: I'm a rag, I'm a rag,
I'm a rag, I'm a rag—time millionaire.
All you little people, take your hat off to me.
Because I'm a ragtime millionaire.

Ever' tooth in my head is solid gold,
Make those boys look icy cold.
I brush my teeth with diamond dust,
And I don't care if the bank went bust.
All you little people, take your hat off to me
Because I'm a ragtime millionaire. CHORUS

Mister Henry's gonna send me a Ford ...(?) [or "forty-..."?]
Ever'body else is gonna take my junk.
Gonna put a little sign on it: "In God We Trust."
I don't mean to have no fuss.
All you....

Some o' the boys say that I'm gonna be late.
No, if you please, I got a twenty-eight.
Some boys say they gonna catch me at last,
But all I got to do is just to step on the gas.
All you....

The following verse was transcribed from a recording by Lighnin' Wells:

Gonna take my sweetie to the ball tonight.
Gonna make all the boys treat her right.
Gonna keep her out about half o' the night.
You know I don't mean to have no fight.
All you....
