Wing Han Tsang, otherwise known as Wing was born in Hong Kong before emigrating to New Zealand. Here's a little about the singer from the bio on her site:

Wing began singing for her own pleasure, and subsequently began entertaining patients at nursing homes and hospitals in and around the city of Auckland where she lives. She was encouraged by the response to her singing to consider making a recording, and with a grant received from Manukau City Council she released a very successful debut CD titled MUSICAL MEMORIES OF Les Miserables and The Phantom Of The Opera, featuring the title song from the Andrew Lloyd Webber musical, along with a number of other popular songs.
