I have 2 songs - "Orgreave" and "Pitworld" which you can hear on my Myspace site -

These songs are included on the Union Songs website, which is an excellent resource and well worth checking out.   

Yorkshire Garland is also extending its base with songs about Working life and Mining - I'm sure he'll read this thread, so Ray Padgett will be able to add more info about that.

Good luck Lucy - there's a lot of good material out there!
