I have nothing to add to this other than I literally recite "The Jumblies" to my son every night to put him to sleep, and its the only thing that works.

I can see why the poem struck such a chord with Donald Crowhurst, though. The regret of those that didn't go and experience "the hills of the Chankly Bore" is what frames the ending.

I'm sure he read the poem to his son, too, and I could understand why the journey would have scared them both.

I thoroughly recommend Samuel West's reading from CBeebies if you are able to find it.
