This time I figured I should identify who sings what.

IT'S IN THE BAG
Words by Charles Tobias, music by Al Sherman, 1927
As sung by Billy Jones & Ernest Hare (The Happiness Boys)

[EH] Say, Bill, I feel immense; I've got confidence.
[BJ] And when you've got confidence, you must feel immense.
[EH] Not a bit in doubt what it's all about.
[BJ] Now, if I mention someone's name— [EH] You're gonna hear me shout:

[EH] It's in the bag; my baby loves me now.
[BJ] It's in the bag; that means you're sure, and how!
[EH] One time she had me worried that there was someone else.
[BJ] Now you don't fear; the coast is clear. [EH] Ha-ha-ha-ha-ha!
It's in the bag; her mama said okay.
[BJ] And did her pa say, "Don't let it drag"?
I'll bet you feel satisfied [EH] and you won't hear me brag
Till I hear the parson say: [BOTH] "It's in the bag."

[BJ] Say, you must be bright. [EH] Well, I'm not a fool.
[BJ] Where'd you get your wisdom from? [EH] I got it all in school.
[BJ] Ah, you're in love with she? [EH] And she's in love with me.
[BJ] Well, do you love each other? [EH] Why, it's plain as A-B-C!

[EH] It's in the bag; she's got a hundred thou.
[BJ] It's in the bag; how can I use some now?
[EH] Well, I'm not the kind that's selfish. [BJ] After you are wed,
Will you get half? [EH] Don't make me laugh! Ha-ha-ha-ha-ha!
It's in the bag; [BJ] you'll buy a bungalow
[EH] That I will pay for [BJ] with all her dough,
[EH] And maybe in a year or so, [BJ] the stork will write a tag.
[BOTH] Near the package he will say: "It's in the bag."

[BOTH] Ha-ha-ha-ha-ha! Ha-ha-ha-ha-ha!
Ha-ha-ha-ha-ha! Ha-ha-ha-ha-ha!
Now take a politician; he'll tell you with a grin:
"I know who'll win; I'll let you in."
Ha-ha-ha-ha-ha! Ha-ha-ha-ha-ha!
Ha-ha-ha-ha-ha! Ha-ha-ha-ha-ha!
[BJ] We know who'll be elected, and we don't mean to brag:
[EH] A republican or democrat! [BOTH] Ha-ha-ha-ha-ha! It's in the bag!
