Lyrics:

I wonder, wonder who, bi du du, who
Who wrote the book of love
Tell me, tell me, tell me
Oh, who wrote the book of love
I've got to know the answer
Was it someone from above
I wonder, wonder who, bi du du, who
Who wrote the book of love
I love you, darling
Baby, you know I do
But I've got to see this book of love
Find out why it's true
I wonder, wonder who, bi du du, who
Who wrote the book of love
Chapter One says to love her
You love her with all your heart
Chapter Two, you tell her
You're never never never never ever gonna part
In Chapter Three remember
The meaning of romance
In Chapter Four you break up
But you give her just one more chance
Oh, I wonder, wonder who, bi du du, who
Who wrote the book of love
Baby, baby, baby
I love you, yes I do
Well, it says so in this book of love
Ours is the one that's true
I wonder, wonder who, bi du du, who
Who wrote the book of love
Tell me, tell me, tell me
Oh, who wrote the book of love
I've got to know the answer
Was it someone from above
I wonder, wonder who, bi du du, who
Who wrote the book of love
I love you, darling
Baby, you know I do
But I've got to see this book of love
Find out why it's true
I wonder, wonder who, bi du du, who
Who wrote the book of love
Chapter One says to love her
You love her with all your heart
Chapter Two, you tell her
You're never never never never ever gonna part
In Chapter Three remember
The meaning of romance
In Chapter Four you break up
But you give her just one more chance
Oh, I wonder, wonder who, bi du du, who
Who wrote the book of love
Baby, baby, baby
I love you, yes I do
Well, it says so in this book of love
Ours is the one that's true
I wonder, wonder who, bi du du, who
Who wrote the book of love
