In 1960, he attended Guildhall School of Music and Drama, London,[1] and began his acting career in one of the UK's first live television soap operas, Home Tonight,[2] with David Hemmings.
Then, in 1973, Prebble joined Capital Radio, the first legal commercial music station in the UK, where he hosted a daily news magazine programme London's Day.
In 1996, he was a lead actor for a year (as the villain Martin Chedwyn) on the American daily soap opera As the World Turns.
[3] Reviewing the audiobook edition of Jasper Fforde's The Big Over Easy in 2005, Publishers Weekly found that: "Prebble's sonorous British voice is ideally suited to narrating this whimsical, fractured fairy tale; his tone and pacing match Fforde's prose perfectly, and his subtle vocal acrobatics enable him to amusingly bring to life the novel's wildly divergent cast of characters.
Nominated seventeen times for the 'Audies' (the audiobook 'Oscars'), he was finally awarded a coveted 'Audie' in 2010, the year he was also named Booklist's 'Voice of Choice'.
