Many UK bands were originally either works bands or sponsored by various industrial concerns. This was particularly evident in coal mining areas, for example, bands such as the Grimethorpe Colliery Band and Carlton Main Frickley Colliery Band in Yorkshire. Bands sponsored by factories include The Black Dyke Mills Band, Yorkshire Imperial Band (originally the Yorkshire Copperworks Band), Foden's sponsored by the truck manufacturer, Fairey sponsored by the aircraft manufacturer, and Leyland Band sponsored by the vehicle manufacturer. One of the reasons for this was to keep the workers from organizing in radical groups. With the decline of these industries several bands have dissolved and others now draw their membership from other industries and other parts of the community. The Brighouse and Rastrick Band, is unique in having operated continually at the highest level without sponsorship, drawing its income from regular concerts, public donations and sales of recordings and merchandise.
