I just watched the episode The Doctor’s Daughter. (A review will appear in another article here later tonight.) [Update: review now up, click here for review.]
I was unsure whether there was a musical reference to Blake’s 7 when the Doctor teleported in The Sontaran Stratagem/The Poison Sky.
However, it seems very likely now, since Jenny appeared with a musical reference to The Hitchhiker’s Guide to the Galaxy.
(Jenny played by Georgia Moffett, the daughter of Peter Davison and Sandra Dickinson who was Trillian in… The Hitchhiker’s Guide to the Galaxy.)
Has Murray Gold referenced any other shows?
