A day after braving tear gas, pepper spray and baton charges, the Hong Kong pro-democracy protesters were in a festive mood as they occupied key parts of the city following the police's withdrawal.
As they indulged in mass sing-along sessions on the streets, one song was clearly the crowd favourite: Canto-rock band Beyond's Boundless Oceans Vast Skies.
Here are five things you need to know about the ballad that has captured the imagination of Hong Kongers staking out Central, Causeway Bay, Admiralty, Mong Kok and other iconic locations.
1. The monster hit was released in 1993 and the fact that many of the student protesters belting out the lyrics by heart were not even born then, is testament to the song's enduring popularity. Indeed, the song is just over two decades old while student leader Joshua Wong is just 17.
Everything in the video, from the floppy fringes to the baggy shirts worn over inner T-shirts, screams the 1990s.
2. As for the lyrics, why have the words been etched so deeply in the collective memory of Hong Kong society? For one thing, the lyrics are highly literary, alluding to one's struggles to stay true to one's ideals while facing the inevitable headwinds and storms in life.
The chorus translates roughly as:
Forgive me for loving freedom all my life,
Though I'm afraid of falling one day,
Anyone can give up one's ideals,
But I won't fear even if there's just you and me.
These are sentiments that the demonstrators no doubt identify with, having been battered by the elements of searing heat in the afternoons and sudden downpours at night over the last few days.
3. Supporters of the Umbrellas Movement have adopted the song as their rallying cry. Its ubiquity is not just on the streets, but online as well. For instance, this three-minute video makes its sympathies clear as it pairs aerial footage of the throngs of protesters with background music from the slow-rock ballad.
4. The band's lead vocallist and guitarist Wong Ka Kui wrote the song as an indictment of Hong Kong's music industry in the 1990s, reported the Wall Street Journal.
5. Tragically, it was Wong's last song with Beyond. The star fell off a stage during a Japanese game show in Tokyo and died at the height of the band's popularity in the same year the song was released. The rest of the members - Wong's brother Wong Ka Keung, Yip Sai Wing and Paul Wong - moved on to solo careers after his death but never found the same success they enjoyed as Beyond.
