Hudson made his debut with the English Chamber Orchestra at Wigmore Hall in London. In addition to a number of concerts at that orchestra, he also conducted for the London Philharmonic Orchestra and the Royal Philharmonic Orchestra at the Royal Festival Hall. He also worked with Laurence Olivier at the Royal National Theatre. He worked with ballet companies as well, including The Royal Ballet at Covent Garden, London, and the Paul Taylor Dance Company in New York City, United States. Besides the United States and the United Kingdom, he conducted orchestras in over a dozen countries over the course of his career, including France, Austria, the Netherlands, Germany, Russia, Bulgaria, the Czech Republic, Canada, and South Africa. Hudson left England for Cape Town, South Africa, mostly for health reasons. There, he conducted the Cape Town Philharmonic Orchestra in the late 1960s and early 1970s. He came to Bulawayo, Rhodesia, in 1973 to work as a visiting conductor for the Bulawayo Philharmonic Orchestra. He was appointed to the position full-time in 1974. During his tenure, the orchestra expanded its reach, touring cities like Gwelo, Fort Victoria, Salisbury, and Wankie. In 1976, he became Director of the ZimbabweAcademy of Music. He played a large role in the founding in 1977 of the National Symphony Orchestra. In 1980, he appeared with National Symphony Orchestra at Zimbabwe's independence celebrations, performing his own composition Prelude: Zimbabwe, as well as Ludwig van Beethoven'sNinth and Tenth symphonies, Edward Elgar's Enigma Variations, and Benjamin Britten's Noye's Fludde. Hudson conducted, but also performed as a soloist and accompanist. Being able to perform Beethoven's Ninth Symphony was no easy feat for Hudson and the orchestra, as the tune was used in Rise, O Voices of Rhodesia, the national anthem of the white-ruled Rhodesia. Only after prolonged negotiations with the government was he able to gain permission to perform it, for the first time in independent Zimbabwe's history. Hudson had a strong influence on musical life in Bulawayo, and was prominent in Zimbabwe as a conductor, lecturer, writer, and broadcaster, even serving for seven years as a member of the Board of Governors of the Zimbabwe Broadcasting Corporation. In 1983, he oversaw the completion of a small concert hall at the Zimbabwe Academy of Music in Bulawayo. In 1997, he initiated the first Bulawayo Music Festival, in which around 150 attendees took a steam train to Victoria Falls, where they witnessed English violinist Tasmin Little perform. After suffering a heart attack in 2001, he retired from public life. After his wife's death in 2003 and due to his own failing health, he left Zimbabwe and moved to Johannesburg, South Africa, to live with his daughter. There, he died in his sleep on 20 December 2005, after contracting pneumonia. In his memory, a new audio-visual centre was set up at the Zimbabwe Academy of Music, which was lacking modern equipment. The new centre, along with a bust of Hudson, by local sculptor Gilliam Kaufman, were inaugurated in October 2007 at the Bulawayo Music Festival.
