'Imagine Flash Mob' for World Peace Day 2017 in Leicester Square

It is becoming a habit for us to do flash mobs on World Peace Day (21st September). Last year, we and our instruments were boiling in the sun on Folkestone beach. This year, it was the London rain that we (and our instruments!) endured... But we still managed to perform our special arrangement of 'Imagine' twice. We want to do more of this!
