Meg Davis is around and online, though her health's a bit under the weather and she says she doesn't perform as much as she used to.The song is, unsurprisingly, on her album CAPTAIN JACK AND THE MERMAID, and songbook ditto, which are both still available, so it's not really ethical to post lyrics and tune here for free without her permission.
