Michael Berkeley's guest today is the playwright Lee Hall, best known as the writer of the smash hit film and musical 'Billy Elliot', as well as the radio play 'Spoonface Steinberg' and the stage play 'The Pitmen Painters'. Some of his musical choices reflect his north-eastern origins, while others range from Alfred Deller singing Purcell and Maurizio Pollini playing Schumann to works by Conlon Nancarrow and Olivier Messiaen.
