The Sixth Doctor perhaps rightly suspects that he's been sent back to Totters Lane-where it all began- for a reason, and has a fair idea who set it in place. Cybermen from the far future are planning to ensure Earth is no more by 1985, engineering events so that Halley's Comet will obliterate it. And obviously that would be very bad for the timeline. So he's forced to halt his repairs to the TARDIS Chameleon Circuit. While his performance of Bach's 'Toccata And Fugue' is very nice when it takes pipe organ form his dip into classical waters is short-lived, perhaps rightly so! There are a number of interesting musical facts here. The audio accompaniment to the Doctor and Peri's viewing of the comet is a selection of composer Malcolm Clarke's work from an earlier BBC science documentary 'The Comet Is Coming'. And in a neat nod to 'Who' theme composer Ron Grainer a distorted version of his 'Steptoe And Son' theme is playing when the TARDIS first lands in the junkyard. Crisis is averted thanks to the Doctor turning the Cyber-Controller's gun on itself and its cronies, avenging the death of undercover policeman Russell (who's played by Terry Molloy, perhaps more famous in the Whoniverse as Davros). And just three stories afterward Six would meet his earlier Second self for 'The Two Doctors' so its hard not to suspect the CIA had a hand in it all. Conveniently we'll be examining all that in more detail next, so thinking caps on (stovepipe hat or a Tam o'Shanter encouraged for that very purpose since you ask). What more logical next stop than an encounter between the two incarnations arguably most prolific as agents of Intervention?
