What is this thing called love?
This funny thing called love?
Just who can solve its mystery?
Why should it make a fool of me?

I saw you there one wonderful day
You took my heart and threw it away
That's why I ask the Lord in Heaven above
What is this thing called love?

I saw you there one wonderful day
You took my heart and threw it away
That's why I ask the Lord in Heaven above
What is this thing called love?

Transcribed by Todd Peach

Following is another version with additional verses:

I was a hum-drum person
Leading a life apart
When love flew in through my window wide
And quickened my hum-drum heart
Love flew in thorugh my window
I was so happy then
But after love had stayed a little while
Love flew out again

What is this thing called love?
This funny thing called love?
Just who can solve its mystery?
Why should it make a fool of me?
I saw you there one wonderful day
You took my heart and threw it away
That's why I ask the Lawd in Heaven above
What is this thing called love?

You gave me days of sunshine
You gave me nights of cheer
You made my life an enchanted dream
'Til somebody else came near
Somebody else came near you
I felt the winter's chill
And now I sit and wonder night and day
