As if superstars Andy Lau and Jay Chou weren't enough to send Mandopop fans into a frenzy, last night's (May 11) online charity concert to thank nurses and commemorate International Nurses Day threw in another surprise. 

Homegrown singer-songwriter JJ Lin made an unannounced appearance during Jay's segment, performing two songs, Fragrance of Rice and Stay With You, together. But you'll be forgiven if you missed it; the duo appeared only close to four hours into the 274-minute-long livestream concert.

So, we have picked out their performance — as well as others from the night's biggest stars — for you to watch here.
