Lyrics:

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 how are your dreams? whatever lover they may be
so how are your dreams? whatever lover 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
