Georgia swiftly kills him with a knife.
No she doesn't.
I've just finished the book. Loved it, thanks for pointing us in its direction but apart from the title, I think it has little to do with the song.
In the book, Chilly Clito (not his real name) and Georgia tussle a bit in the dark at the end, he tries to put her eyes out (not nice!) breaks her little finger, but she escapes, while he is captured and locked up in a loony-bin -as he is actually completely mad, in a rich, facist good looking way- . All this after an inordinate amount of time spent flirting, flying around and many other quaint, far-fetched, hilarious adventures.
She does try to finish him off by starting a fire in his stately home at one point, but fails. Ah well. It's the thought that counts...
So anyway, some ladies into paragliding and scones here might find this book charming too, but I can't enlighten you on the meaning of the song. I agree it's likely to be about penises, which bores me senseless, personally, but there you go.
Looks like there's a book by Julio Cortazar with that title too, if you wish to investigate that. I for one can't be bothered, I just like simple literature like wot Cecil writes.
Next up: "the Camp Summer Mystery." Aye...Should keep us busy...
