Night Mail

Sir: If Giles Gordon (`On the rails, and off,' 7 April) is going to enter the field of the cinema he, too, must stay on the rails. The score, the music, for Night Mail was by Britten: Auden wrote the verse: the sound was devised and recorded under the supervision of Alberto Cavalcanti: Harry Watt with Basil Wright to help him directed the film. Roger Manvell's Film, revised edition 1946, give the precise details.
