Searching the www for local pit bands and their banners Google threw up a site, Internet Bandsman's Everything Within (IBEW) that collects colliery brass band photos from the UK AND the rest of the world. I have been in contact with the web sites owner/webmaster, Gavin Holman and is aim is to allow everyone, in the world, access to the site and the info that has been gathered - extract of email from Gavin :- 'Alan Feel free to use any of the images as you wish. I'm happy to support any initiatives that maintain the links to the past and preserve memories etc.
Of course, in years gone by, the miners' picnics were a major feature of the life of the pits in the north. It is sad that none remain (as far as I know) and only the Durham Miners' Gala exists as a reminder of the hundreds of pits, miners and bands of the past.

Unfortunately I could find no additional info to go with the each named photo - wysiwyg.
