Hollow Bones

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
