Around 1860, when the army Volunteer Force was established in Britain, a number of the rifle and artillery companies raised brass bands (and drum & fife bands) to accompany their parades. At the same time, the Police Force was starting to form brass bands among some of its divisions, firstly in London and gradually spreading to other major cities. 75 such bands are known to have existed over the last 160 years, with nine constabulary bands still being active today (Covid notwithstanding!).
The British police forces have been protecting the population for over 200 years. Some of them have also been entertaining audiences through their brass and concert bands.
The following paper gives some details of this corner of the brass band world.
