Who? Jerome Kern

(Verse)
When a boy's in love with someone
He must indeed be a dumb one
If her secret he cannot unmask
When a girl's in love with someone
She must wait until there comes one
Boy who knows the answer when she asks

(Chorus)
Who
Stole my heart away?
Who
Makes me dream all day?
Dreams I know
Can never come true
Seems as though
I'll ever be blue
Who
Means my happiness?
Who
Would I answer "yes"
To?
Well, you ought to guess who
Who?
No one but you
