Many of the most instantly recognisable works in classical music are inspired by the Earth’s moon – Debussy’s ‘Clair de Lune’, Beethoven’s ‘Moonlight Sonata’, Dvořák’s ‘Song to the Moon’. Tom Service takes us on a musical voyage to the moon (and back), from the cosmic-scale classical to the lesser known music invoking and inspired by our mysterious celestial companion. With Professor Monica Grady CBE, leading British space scientist. Producer: Lola Grieve
