The beginning of this track is the first use of a lesser known motif that reoccurs in all 4 of the RTD series (see my Labor Camps video for another use of it) . It's followed by a variant of a track from Dalek, from the scenes where both the Dalek and guards are electrocuted. Then we have another piece which is used in both the series 1 and 2 finales and then it ends on a somber piece which appeared in both Parting of the Ways and Father's Day.
