You can hear that in the 'Battle in the Air' in Walton's 'Battle of Britain' where parts just leap out shouting 'Malcolm Arnold' who orchestrated it.
Bad example. The parts of the score that sound like Arnold were written by him. Walton's bits were orchestrated by Walton himself...
The march introduction is also by Arnold and few other short bits.
The credits are quite misleading as the march was conducted by Walton (Arnold handed the baton over to him).
Arnold didn't want anything except a conductor credit, remember inspite of the age gab they were very close friends since the early 40ies.
