The march was broadcast often by BBC Radio during World War II, especially when programming was directed to occupied Denmark, since the march symbolised a connection between those two countries. The broadcasts were introduced by the first bars of the tune voiced over by the words ""Her er London. BBC sender til Danmark"." ("This is London. BBC is broadcasting to Denmark.") In Denmark the march thus became strongly associated with the opposition to Nazi occupation and propaganda. It is still performed during the annual celebrations of the liberation. For many years, the Trumpet Voluntary remained the European Service signature tune of the BBC World Service.
