A 1974 Christian hymn called "Sing Hallelujah to the Lord" has become the "unofficial anthem" of the anti-extradition protests as it was heard everywhere at the many protest sites during the early stage of the protests. "Do You Hear the People Sing", the unofficial anthem for the Umbrella Movement in 2014, has also resurfaced as a commonly sung song during the protest. A group of anonymous composers has written the song "Glory to Hong Kong", which became the theme of the protest and was regarded as Hong Kong's unofficial national anthem by protestors. On the same night, the song was also publicly sung at more than a dozen shopping malls across Hong Kong.
