Free-for-all flash mob choir hits the right note for Sydney's closet singers

The sound of 700 IT workers, consultants, teachers, hipsters and retirees belting out the best of Gloria Gaynor at 8am on a sour summer's day in Sydney, is better than it might seem. Their voices are untrained, unpolished, unheard-of. They have come cradling hopes and takeaway coffees. They have come in activewear and smart casual. They are not singers but this is their choir.
