Lyrics:

Writer(s): Gus Kahn/Walter Donaldson


(first words replaced by trumpet notes)
***, that's my baby
No sir, I don't mean maybe
Yes sir, that's my baby now

Yes, ma'm, we've decided
No ma'm, we ain't gonna hide it
Yes, ma'm, you're invited now

By the way, by the way
When we walk up to the preacher I'll say

Yes sir, that's my baby
No sir, I don't mean maybe
Yes sir, that's my baby now

(instrumental interlude)

By the way, by the way
When we run into the preacher I'll say

I'll say yes sir, that's my baby
No sir, I don't mean maybe
Yes sir, that's my baby now

Mmm
