International reggae star Fiji, real name George Veikoso, was on stage at this year's One Love Festival when he began to rouse the crowd to join in as he sang E Papa Waiari.
A video taken on stage by one of his team, Bernz Talanoa, has tonight racked up more than half a million views.
As the camera sweeps across the masses, they sing together: "E papa waiari, taku nei mahi, taku nei mahi, he tuku roimata.
"E aue, e aue. Ka mate au. E hine, hoki mai ra,'' the crowd sings.
Thousands of people have shared the video, with many commenting about its uniqueness.
