Birth of Narnia # 1 - by Paula Novak
“A voice had begun to sing. Sometimes it seemed to come from all direction at once. It was, beyond comparison, the most beautiful noise he (Kabby) had ever heard,” - Chapter 8, The Fight at the Lamp Post.
“Thus with an
unspeakable thrill Polly felt quite certain that all the things were
coming (as she said) “out of the Lion’s head”. When you listen to
his song you heard the things he was making up; you looked around you,
you saw them.”
Magician’s Nephew, Chapter 9, The Founding of Narnia.
