Hoodoo Gurus - Castles In The Air lyrics

Once I built a castle in the air A home for you and I- In a blue, blue sky We'd leave behind the weight of worldly care I thought we could fly We only had to try Ah, I had to learn fast, (For your own good) I had to learn fast And when I knew at last (You understood) I knew at last Hell and heaven can be one and the same If you don't know how You should know by now Every pleasure always holds an equal amount of pain But it all works out I have no doubt Ah, we had to learn fast, (For our own good) We had to barn fast And when we knew at last (When we understood) We knew at last Every kite has got to have a string for it to fly Up to who knows where ? Castles in the air So there are strings attached to you and I Though they hold us tight We can take flight
