The Bataclan concert hall in Paris has become the scene of the worst violence to hit France since the Second World War.

Isis claimed responsibility for the attack on Friday night, calling the city a “capital of prostitution and obscenity.”

The terror group appears to have targeted entertainment sites - a rock concert at Bataclan, a football match attended by President Francois Hollande, and several bars and restaurants - accordingly.

Targeting the French way of life, however, has only made Parisians more determined to show their joie de vivre.

On Saturday morning a man cycled to the famous Bataclan music hall towing a baby grand piano, reporters at the scene said.

Once he was all set up, he played the famous pacifist song "Imagine" by John Lennon for the crowds of mourners gathered at the spot:

The anonymous man is not the only person to use music to restore people's faith in humanity in the wake of the tragedy.

Even as crowds were being evacuated from the Stade de France on Friday night, many supporters began singing the French national anthem "La Marseillaise" in a show of patriotic solidarity.
