Into the Wardrobe

Does anyone recognize this quote. It is likely not quoted exactly correctly. My mother received it from a friend of hers. My books are in storage so I cannot try and find it myself.

"I am not a body with a soul, I am a soul with a body"

If anyone could provide any identification or a small bit of context I would really appreciate it.

Thanks very much for your help.

Are you sure it wasn't Louis Prima?

"I ain't got no body..."

Heh. :)

galion is right: it's not Lewis, it's Walter Miller.
