Northern Ireland fans sing Will Grigg's On Fire chant at Euro 2016

Several hours before their Euro 2016 opener was due to kick off in Nice, crowds of Northern Ireland supporters flooded into the streets to serenade the locals with a rousing rendition of their latest anthem.

Sure enough, it wasn't long before a lively chorus of the chart-busting "Will Grigg's On Fire" chant was reverberating through the town.

Fantastic stuff!
