"...Coal miner kept down too deep"

"...Found this blues harp in my shirt
Lonely note works up through the dirt
Canary, yellow-black
Won't sing, just beating wings"

Craig wrote: "Rob had one evocative piece of music he had titled 'Harmonic Minor' as it used a harmonic minor scale. My brain spun off into 'Harmonica Miner.' A miner is trapped underground and while laying in what could be his final resting place he finds a harmonica in his breast pocket. He draws a note and it echoes into the distance and takes him to the world above. A harmonica evokes the lonely cowboy at a campfire on the plane or a train heading off to a fresh start."

Canary's were used as warning signals in the days before high tech detection and monitoring equipment. If a Canary died in it's cage, coal miners knew an invisible threat of gas or some other air impurity had reached their area.
