Choirmaster Gareth Malone returns to create harmony in five of Britain's biggest workplaces. As the contest to be crowned 'best workplace choir' continues, Gareth travels to Birmingham to the biggest council in Europe. He discovers a singing traffic warden, a social worker soloist and a high-pitched gardener. With the next round of government cuts announced mid-rehearsals, some choir members may not have jobs at the end of the year.
