Hi Natasha
This response is probably late....but here we go.
I was a kid in a brass band, in a mining community, in the middle of the miners strike.
The miners strike and subsequent closure of access to the national coal resource did not affect 'the brass band world' as much as it affected the order of the nations economy.
Brass bands although a proud figurehead of any given mining community were not dictated to by politics. 'The band' was held above such nonsense in the eyes of men, women and children alike. All knew the brass band, 'their brass band' was simply a beacon of beauty within a hard, cold and dark world.
The world is still hard, cold and dark.
A brass band still brings beauty.
And so the movement continues, not only for the memory of the mines and the men who worked them but for the celebration of life. as it always was and still is.
Any man can join a brass band.
To create music.
Well, thats the Catherine Cookson bit out of the way.
Funding.
Brass bands were never money making machines.

never!?
"whether band has been profitable" profitable? .... I just don't get it?
With some exceptions, the majority of bands are probably subsidized by their own members to a large extent weather they are successful or not.
"Performing Rights Society etc. " 
....as I see it any man has the right which is fundamental to the movement. If anything is immune to the categorization and red tape lock knots imposed on what we hear in this repressed audio world its a Brass Band.
‘Brassed Off’,

In my opinion accurate on all levels except one...... Ewan McGregor's valve combination miming was pathetic.
