Lyrics:

Oh I wonder wonder who (ma doo doo) 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
Is it someone from above

Oh I wonder wonder who (ma doo doo) who
Who wrote the book of love.

I, I love you darling
Baby you know I do
But I've got to see this book of love
To find out why it's true.

Oh I wonder wonder who (ma doo doo) who
Who wrote the book of love.

Chapter one says you love him
You love him with all your heart
Chapter two you tell him
You never never never never never want to part
In chapter three remember
The meaning of romance
In chapter four you breakup
But you give him just one more chance

Oh I wonder wonder who (ma doo doo) 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.

Oh I wonder wonder who (ma doo doo) who
Who wrote the book of love.

I wonder who yeah who yeah who yeah
Who wrote the book of love
Who wrote the book of love
Now who wrote the book of love
