WATCH: ‘Je Suis Charlie’ Protesters Sing ‘Imagine’ in Unison

On January 11, over 1.5 million people marched in Paris, France in solidarity with free speech and in protest of the Charlie Hebdo terrorism.

As the crowds gathered in Place de la Republique (Republic Square), a Redditor whose apartment overlooks the iconic location decided to put on some music, specifically “peace music.”

Watch what happened when John Lennon’s Imagine came on.
