i met a girl traveling 'round the world, leaving pieces behind  she said she'd wait for me, i can't make her see that she's called to other skies  i can't be her place to hide    it's comin' up, it's comin' up again (live here long to make her stay)  and what are you doin' in my head? and why did you call me when you're dead!? (go on!)    so go on, go and take on the world (building castles, building castles!)  expand your wings across the sky, take my words and say good-night and never say good-bye    maybe in another time, you could have been mine  expand your wings and fly and look to the sky    it's comin' up, (don't forget to write me) it's comin' up again  indulge in everything you'll see (what are you doin' in my head?)  and why did you call me when you're dead!? (go on!)    so go on, go and take on the world (building castles, building castles!)  expand your wings across the sky, take my words and say good-night and never say good-bye    so follow all your dreams whatever, whatever they may be  so follow all your dreams whatever, whatever they may be (go on!)    so go on, go and take on the world (building castles, building castles!)  expand your wings across the sky, take my words and say good-night and never say good-bye    expand your wings and fly and look to the sky  expand your wings and fly  expand your wings and fly
