What Is This Thing Called Love? Cole Porter, Leo Reisman (#5 in 1930), Ben Bernie (#10 in 1930)

What is this thing called love? This funny thing called love?
Just who can solve it's 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 up in Heaven above
What is this thing called love?
