Boy, coal miners were a singing bunch!
With all of these songs, there's one of my favorites that no one has mentioned, and that's THE SHOOFLY.

As I went a-walking one fine summer's morning,
It was down by the furnace I chanced for to stroll.
I spied an old lady, I'll swear she was eighty,
At the foot of the dirt bank, a-looking for coal.

ETC.
