Lyrics:

Album liner notes:\'The six notes of the Cybermen theme can't really be separated from the clump of their marching in formation. This, as much as the music, signalled their ominous advance. Nevertheless, those six notes do underscore much of the Cubermen on screen in Tom McCrae's brilliant two-parter. I was always amazed that some people were actually more frightened of the Cybermen than the Daleks themselves. After Series 2, I get it.\'
