The Choir of Hard Knocks became a household name when it burst onto television screens in 2007, making rock stars out of 50 of the most unlikely people. Front and centre, clapping and crying, was its choir master Jonathon Welch. Made up of the homeless, drug addicts and alcoholics, the choir sold out concerts at the Sydney Opera House, amassed an Aria award and a gold album. But long after the cameras stopped rolling, Jonathon kept the choir going on his own. Now as Jonathon bids farewell to his beloved choir, he reveals the deeply personal reasons behind his departure.
