Nearly all british boys in the first half of the last century were a member of some boys organisation. If you went to a private school (called a Public School) this was often a junior branch of the armed forces where you had the chance to get your hands on a real gun and practice killing people. Less violent options were to join the Boys Brigade or become a boy scout. There are many clips at pathe showing the Boys Brigade and Scouts, many of which include singing, such as round the camp fire etc. but it is of low quality. The Boys Brigade was more popular in the 30s but by the 50s scouting had taken over.

The easiest way to locate the videos at British Pathe Films is to go to the advanced search and feed in the films ID number which is given here.
