Bernard Levin in conversation with Aaron Copland , the grand old man of American music commonly regarded as the greatest of all their composers, he has written such pieces as Fanfare for the Common Man, Appalachian Spring, Billy the Kid and The Pied Piper ballet; late in life he has also won acclaim as a conductor.
