In a programme first broadcast in 2017, Tom Service explores arguably the most famous piece of music in the world: the Ode to Joy from Beethoven's Ninth Symphony. It's a piece which has been appropriated by everyone from the European Union, to the writer Anthony Burgess, who used it as an unsettling counterpoint to the murderous exploits of the characters in his novel A Clockwork Orange. Tom asks whether Beethoven's original vision of a musical utopia has actually turned out to be far more dangerous than the composer could ever have imagined.
