Lyric discussion by irdonnelly 

Cover art for The Astronaut lyrics by Something For Kate

I think it's about someone who you see as being completely full of themselves, maybe the tall poppy syndrome. 'I'll blow you out of the sky if you don't get yourself down here' is basically saying you'd be such a beautiful person if your head was to become a little less swollen. I give up trying to figure out what Paul thinks, as beautiful as his mind is, but that's my thoughts anyway.
