#5 Murray Gold did the music. His beautiful scores are cinematic, epic on a grand scale. And yet, for this little slice of nostalgic fun, Murray Gold scrapped his soaring orchestras and multi-layered harmonies in favour of an 80's style symphonic score. It adds to the overall effect, another direct little nod to a past era of this huge show. Just check out the little "Dun dun DDUUNNN!" bit when it's apparent the TARDIS will create a Belgium-sized hole in the Universe. Wonderful.
