Lyrics:

I wonder, wonder who, who-ooh-ooh, 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

(Oh, I wonder, wonder who, ummbadoo-ooh, who)
(Who wrote the Book Of Love)

I love you, Darlin'
Baby, you know I do
But I've got to see this Book of Love
Find out why it's true

(Oh, I wonder, wonder who, ummbadoo-ooh, 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, never 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, ummbadoo-ooh, wWho)
(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

(Oh, I wonder, wonder who, ummbadoo-ooh, 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, never 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, ummbadoo-ooh, 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

(Oh, I wonder, wonder who, ummbadoo-ooh, who)
(Who wrote the Book Of Love)
I wonder who (yeah)
Who wrote the Book Of Love
