Halou - Hollow Bones lyrics

I understand the principle Wrapped it up inside my skull I just cannot seem to make it real Downward stroke, back and up Downward stroke, back and up And even without hollow bones And burdened down by all these clothes Against the forces of the Earth I swear that I will make it real And when we go Take nothing with us Southerly And when it's cold Then they will miss us Southerly I have intellectualized Looked at this from every side I just cannot seem to make it fly Downward stroke, back and up Downward stroke, back and up Hush, pretty bird, don't you know you can't sing? Whoosh, little bird gonna take to the sky
