I love brass bands myself but have no musical abilities whatsoever.
Bands were an integral part of any community prior to the arrival of the gramophone and later radio. Even the little railway (all 62 miles of it) in which my family were involved, had a works band . The members of that would have joined Swindon Great Western Railway Brass band in 1923 when The MSWJR was taken over. Currently the GWR band goes under the name Swindon Pegasus Brass band.
Sadly many brass bands struggle to get members as many schools have dropped brass instrument training or come to that any instrument training. Anyway the majority of children who want to learn an instrument want to learn keyboards or Guitar.
