YOU'RE JUST IN LOVE ( I WONDER WHY)
Perry Como
Irving Berlin 
Call Me Madam (1950, Vocal Score)

MAN:  I hear singing and there's no one there
I smell blossoms and the trees are bare
All day long I seem to walk on air
I wonder why, I wonder why
I keep tossing in my sleep at night
And what's more I've lost my appetite
Stars that used to twinkle in the skies
Are twinkling in my eyes I wonder why

HER:  You don't need analyzing It is not so surprising
That you feel very strange but nice
Your heart goes pitter patter
I know just what's the matter
Because I've been there once or twice
Put your head on my shoulder
You need someone who's older
A rubdown with a velvet glove
There is nothing you can take
To relieve that pleasant ache
You're not sick You're just in love

HIM:  I hear singing and there's no one there
HER:  You don't need analyzing , 
HER:  it is not so surprising
HIM:  I smell blossoms and the trees are bare
HER:  That you feel very strange but nice
HIM:  All day long I seem to walk on air
HER:  Your heart goes pitter patter
HER:  I know just what's the matter
HER:  That you feel very strange but nice
HIM:  I wonder why, I wonder why
HER:  Because I've been there once or twice
HIM:  I keep tossing in my sleep at night
HER:  With your head on my shoulder
HER:  You need someone who's older
HIM:  And what's more I've lost my appetite
HER:  A rubdown with a velvet glove
HIM:  Stars that used to twinkle in the skies
HER:  There is nothing you can take
HIM:  Are twinkling in my eyes
HER:  To relieve that pleasant ache
HIM:  I wonder why
HER:  You're not sick you're just in love
HER:  And I know why
HIM:  And I know why
BOTH:  We're just in love
