Wish you could have been in Big Mick's Getaway workshop this weekend on "Songs of the Struggle." Incredible. Some of those songs are intense! -- It was a three-hankie workshop for some of us softies.
Try to include some older songs if you can, maybe Joe Hill? Or Bread and Roses, if it's American.
Sandy Paton sang a song in Mick's workshop which I think is called "My Old Man." It's a gripping song about a man who was killed for union activity. Sandy? Is it on one of your albums? Is it American? (Sounded American.)
Helen Schneyer's albums, if you can find any, contain at least two fine protest songs about American coal mines.
Just for grins I looked up "miner" in the DT. The first song was called "The Day the Coal Blew Away." Take a look, it's a good song & a good story. Not American, though.
