Summary The Sound Barrier: The story of a former high flying businessman on a mission to teach the world to sing. Michael Dale was a gifted opera singer with what looked like a glittering career ahead of him when a freak accident resulted in him losing his singing voice. Forced to abandon singing, he entered the publishing business and ended up test driving high performance sports cars. But he couldn't get music and the joy of singing out of his head, and a chance encounter with a famous conductor resulted in him discovering his talent for teaching others to do what he could no longer do himself ... sing. Michael now works full time at the Sydney Conservatorium of Music as a singing coach. His "clients" range from rock singer Tim Finn, to top opera singers, to taxi drivers. Michael believes everyone can sing. He says it's a birthright and a way of bringing joy into people's lives. He runs regular workshops for adults who believe they just can't sing and who are amazed at the transformation that can be achieved. He has also recently started working with terminally ill people. Michael says: "I'm on a crusade to get Australia singing. People enjoy singing and when they sing together they tend not to be at one another's throats." PLUS:The Sunshine Twins: The story of Dorothy and Moya O'Brien, colourful and cheerfully eccentric twins, who 21 years ago set up a centre which is unique in Australia. It's called the Sunshine Remedial and Welfare Association (SWARA) and it provides work and companionship for intellectually disabled people of all kinds. The centre is a much loved institution in Brisbane and is still run by the twins, who are now elderly ladies. Dorothy and Moya always wear pink and say they see themselves as "twin souls".
