I'm amazed others have read the book - I quite enjoyed that one. And yes I read too that the song was composed for the book, - Though it was in the Authors note at the end of the book.
Which brings on a question - When I read a book - I generally read /browse /quickscan the acknowledgements at the front to see background details etc. - My wife thinks I mad and never heard of anybody reading them ( the acknowledgements )
What of you - or am I alone in this ?? Though sounds like Dicho above does ??
