She reveals that The Bund is the song that keeps on giving. She says: "I have not stopped singing that song for 32 years. It's a miracle really. I sing it with a lot of gratitude in my heart."In 2011, she also received an unexpected windfall of a six-figure sum from the song for digital royalties thanks to the performing rights society in Hong Kong, which had been negotiating a royalties deal with mainland China.
