I happened to be browsing BBC Alba and there is a Folk Prom on tonight which is described as following...

FOLK PROM

Part one. In a Prom that celebrates the history and evolution of the folk music scene in Britain and Ireland, the BBC Concert Orchestra collaborates with Julie Fowlis, the Unthanks, Sam Lee and Jarlath Henderson who are pushing the boundaries of folk music.

It prompts a lot of questions.

Does the BBC know what folk music is?
Can the boundaries of folk music be broadened? (Surely not according to a number of people on this site)
Can, or has, the folk music scene evolved?

See you again round about post #3000
