‘This Light of Reason’ is a touching choral tribute to Jo Cox, who was murdered in June this year
A cellist played Leonard Cohen’s ‘Hallelujah’ while security measures were significantly tightened in the Belgian capital.
The instantly recognisable song was also sung by crowds in Paris over the weekend of the recent attacks that killed 129 people.
The footage of the cellist was captured on Saturday by Twitter user @ElsAmpe:
The terror alert in Belgium has been raised to its highest possible level since Saturday, with major restrictions on public transport and an influx of military personnel.
It's not the only musical tribute related to recent terrorist attacks - last weekend, a pianist arrived on the streets of Paris to perform John Lennon's 'Imagine' .
Leonard Cohen's song has become one of the most covered songs in history, thanks to popular versions by John Cale and Jeff Buckley.
