Why do fools fall in love?

Why do birds sing so gay?
Lovers await the break of day.
Why do they fall in love?
Why does the rain fall from up above?
Why do fools fall in love?
Why do they fall in love?

Why does my heart skip this crazy beat?
For I know it must taste defeat.

Tell me why, why oh why, why do they fall in love?
Why does my heart skip this crazy beat?
Why do they fall in love?

I wonder who wrote the Book of Love.

Tell me, tell me, tell me, who wrote the book of love;
I've got to know the answer,
Was it someone from above?

I wonder who, who wrote the Book of Love.

I really love you darlin', baby you know I do.
I've got to see this book of love,
Find out what is true.

I wonder who, who wrote the Book of Love.

Chapter One says to love her, love her with all your heart.
Chapter Two you tell her, you're never ever, never ever gonna part.
Chapter Three you'll remember the feeling of romance.
Chapter Four you break up, but you'll give her one more chance.

I wonder who, who wrote the Book of Love.

Baby, baby, baby, I love you yes I do.
It says so in this book of love -
ours is the one that's true.

I wonder who, who wrote the Book of Love.
