He started playing the horn at age 13 and within two years landed a position in the Melbourne Symphony; by age 19, he had gone to Britain and played in orchestras there; at age 24, he was appointed first horn in the London Symphony. After 13 years, he left the LSO for a full-time career as a soloist (then, as now, very rare for his instrument), making more than 50 recordings, and developed an additional career as a conductor. – Gramophone
