The Sound of Music
From Tardis Wiki, the free Doctor Who reference
The Sound of Music was a film starring Julie Andrews.
Sylvia Gribbins thought that St Agnes Abbey was "a long way off anything in The Sound of Music" and the nuns didn't remind her much of Julie Andrews, either. (PROSE: Eye of the Gorgon)
The Fifth Doctor saw The Sound of Music at Christmas on TV. (PROSE: In the TARDIS: Christmas Day)
Behind the scenes
According to Russell T Davies, David Tennant went to the theatre with Kylie Minogue, to see The Sound of Music. He wondered why this didn't make the tabloids. (REF: The Writer's Tale)
