Animascope - unknown tracks in 60s demo film

[apmnut]

Anyone recognize the vintage stock music heard in this bizarre demonstration film (besides the ballet music at 3:20, which is a classical piece already ID'd as being performed by the Philadelphia Symphony)? Specifically interested in the British-sounding neutral piece heard beginning at 0:39 or so and heard again throughout the film.
