This song contains great writing. Any fool can write a song, but to write a song with such great lines, and such perception is rare. The way the narrator of the song descibes coming across the Chinese workers in markets and in shop queuses, and wishing he had taken the time to warn them of the dangers in the bay - like his mother had warned him as a young child, is very moving, and a wonderful devise for making the song "real". Excellent.
