Canary in a Mine

I gotta go When that whistle blows it's me who sings Deep and low Like the bond of a wedding ring My wrench turns My body into Something stronger Than it's ever been It's hard, It's hard, It's hard But necessarily so Of course it don't feel too good to me This wrench ain't the same as a hand to hold I've seen something darker than night Just black and the occasional passing light I've seen fear in miners eyes As the canary of their coal mine I feel the cage I feel the weight As the gas takes Its necessary toll I gotta go There will be no more time to sing Deep and low Like the bond of a wedding ring
