That big Blue Moon up there tonight. Second full moon in July. So bright. Makes the sky look blacker than usual. Darker, colder. Go out and look at it. You feel something. Something that our prehistoric ancestors felt, only more strongly. For them, when the moon shone like that, it was time to get back in the cave. Get  out of that bright light. There were things out there, ready to pounce. You had to hide until daylight.

And maybe a million years later a blind man sat on the porch of his house with a guitar and sang a song. A song inspired by that same primordial feeling the cave man felt. That twinge of fear and the need for something to make you feel safe.Or if not safe at least a feeling that there’s something more out there than the darkness and that bright, bright moon shining down. And maybe it sounded like this.
