Can anyone lend me assisstance?

I have this fragment of a James Keelaghan song stuck in my head:

"The last time I saw him/he'd been swallowed by the wood; I'd have followed if I could He'd have stayed had he wanted."

THIS IS ALL I KNOW. IT'S BUGGING THE HELL OUT OF ME. I KEEP SINGING IT OVER AND OVER AGAIN.

Can somebody PLEASE help me out with the lyrics, or at least direct me to a recording of this song? It's eroding my sanity!

Danke, knicke knickerson
