They used to play this (and other similar ones) during rush-hour at Waterloo Station. The perfect example of the psychological power of music 🙂
“The River Kwai March” is a march composed by Malcolm Arnold in 1957. It was written as an orchestral counter-march to the “Colonel Bogey March“, which is whistled by the soldiers entering the prisoner camp in the film The Bridge on the River Kwai and again near the end of the film when the bridge is formally dedicated. The Arnold march re-appears (without the “Colonel Bogey March”) several times in the film and is repeated at the finale.
The two marches have been recorded together by Mitch Miller as “March from the River Kwai – Colonel Bogey”. Due to this, the “Colonel Bogey March” is often mis-credited as “River Kwai March”.
