O TELL ME WHY, DO WE BUILD CASTLES IN THE SKY? O TELL ME WHY, ALL THE CASTLES WAY UP HIGH? i don't know why we build castles o way up high in the sky, but i know that this video and song is in my 2011 jam zone!! i love the throne in the beginning and when the different people's dancing bodies morph together. Ian Van Dahl is a geniuz.
