Bert Williams recorded this as a recitation with musical accompaniment. Accordingly, he embellished it with a few spoken phrases, not shown here, to make it more conversational in tone. From the sheet music at UCLA:


UNEXPECTEDLY
Words by Jim Burris, music by Perry Bradford, ©1922.

1. There's one thing that happens to me and you
When we have something special to do.
It seems like something happens 'fore we get through
Unexpectedly.
On a married lady once I called.
Her husband came; he was six foot tall.
I had to take window sash and all
Unexpectedly.

CHORUS: There is lots of meaning in that one little word:
Unexpectedly.
Now, hootch is another one that's not often heard
Unexpectedly.
I used to drink gin sup by sup,
Then I learned to drink it cup by cup.
Here prohibition came along, messed ev'rything up
Unexpectedly.

2. I got some work in a swell cafe,
And took some fresh meat every day (just a small piece).
The boss got wise to me in some kind o' way
Unexpectedly.
Next morn' judge says: "What have you to say about that?
The boss caught you with chops in your hat."
I said: "Not guilty"; he said: "Six months for that"
Unexpectedly.

CHORUS: I found out the meaning of that one little word,
Unexpectedly.
It seems like I always do the bad for good,
Unexpectedly.
He said if I'd taken a ham or a goose,
He might have found some way to let me loose,
"But for two pork chops let you free?
No; take him; throw away the key"
Unexpectedly.
