Jim Dixon seems to have found one line of lyrics (the first) for an introductory verse, which just makes the whole deal that much more tantalizing.

I sing/play this quite regularly, and use a slightly different set of words to the bridge. I don't remember where I got 'em...

Moonlight on the bayou
A Creole song that fills the air
I dream about magnolias in June
Wishin' I / could soon / be there!
