Peter Purves (Steven Taylor), Tony Millan (the Interrogator)
- Mother Russia was a 2007 audio-play from Big Finish Productions.
- Dodo Chaplet takes up a position as a piano teacher, on the condition that she does not have to play, or hear Steven Taylor sing, “The Ballad of the Last Chance Saloon”.
- Also, Steven is surprised that The Doctor wishes to holiday in Russia, since they have so recently holidayed in Tombstone, Arizona. Taken together, the two facts suggest
- that the events of Mother Russia occur relatively soon after those of The Gunfighters.
- Steven comments that Homer’s writings in The Iliad are “wrong”, and contrasts the French Army with that of the Greeks. (The Myth Makers)
- This audio drama was recorded on 6 June 2007.
- Though the word”isomorphic” never actually appears in the play, Steven’s description of why the TARDIS didn’t work for what he calls”the false Doctor ” clearly indicates that the controls are supremely isomorphic – able to tell the difference between the real Doctor and an extremely good copy.
