Perry Como
You're Just In Love (I Wonder Why)
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 ?

You don't need analyzin'
It is not so surpisin'
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 rub-down with a velvet glove!
There is nothing you can take
To relieve that pleasant ache
You're not sick, you're just in love!

Repeat verse and chorus simultaneously

Now you know why!
Now I know why!
I'm just in love!
