The 1945 film "Battle for Music" told the story of the London Philharmonic's trials and tribulations during World War II. Several classical artists took part, including Sir Adrian Boult, Benno Moiseiwitsch, Eileen Joyce, Constant Lambert and Dr. (later Sir) Malcolm Sargent. This clip is of Sargent conducting Delius's "La Calinda" for an audience of school children.
