Traditional

Some blues are just blues, mine are the miner's blues

My troubles are coming by threes and by twos

Blues and more blues, it's that coal black blues

Got coal in my hair, got coal in my shoes

These blues are so blue, they are the coal black blues

For my place will cave in and my life I will lose

You say they are blues, these old miner's blues

Now I must have sharpened these picks that I use

I'm out with these blues, dirty coal black blues

We'll lay off tomorrow with the coal miner's blues
