The first version here is from the sheet music at Johns Hopkins University (Levy Collection):


CONSTANTLY
F. Ziegfeld Jr's revue Follies of 1910.
Words by [Harry Bache] Smith and [Jim] Burris, music by Bert Williams, ©1910.

1. I used to be a lucky moke.
A-spending money was a joke,
But now it seems dat I stay broke
Constantly.
I never was troubled with my landlord befo'.
My rent he always said was sho',
But now he's knocking at my do'
Constantly.

CHORUS: Good luck wans [sic] me, dorns [sic] me, scorns me,
Constantly.
Bad luck meets me, seeks me, greets me
Constantly.
Sometimes I feel like a bird in a tree,
Flyin' round so gaily and free,
But it seems hard luck clips my wings for me
Constantly.

2. As a prize fighter once I thought I'd try.
I fought a man they called Kid Nye.
Dat man he sho' did find my eye
Constantly.
I thought I'd win myself some dough.
Ten rounds I thought I could stay sho',
But the referee was pickin' me offen de flo'
Constantly.


[Here's how Bert Williams actually sings it. You can hear his recording at The Internet Archive:]

1. There is a word called mis'ry,
And mis'ry loves company.
That's the reason why it chases me
Constantly.
My landlord never bothered me befo',
Always said that my rent was sho',
But now he just knocks on my do'
Constantly.

CHORUS: Good luck eyes me, spies me, guys me
Constantly.
Bad luck seeks me, meets me, greets me
Constantly.
Sometimes I feel like a bird in the tree,
Flyin' round so gaily and free,
But it seems hard luck clips my wings for me
Constantly.

2. At prize fights once I thought I'd try.
I would fight a man that they called Kid Nye.
The man just kep' his fist in my eye
Constantly.
The fight only had about six rounds to go,
And there I was, and I needed the dough,
But the referee jus' kep' pickin' me off o' de flo'
Ooh, constantly.

CHORUS: Good luck eyes me, spies me, guys me
Constantly.
Bad luck meets me, seeks me, greets me
Constantly.
That man he sho' did have the knack
Of jus' shootin' 'em in like the kick of a jack.
When it hit me in the stomach, I'd bulge out in the back
Constantly.
