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!

Now you know why!

Now I know why!

I'm just in love!
