Singer (Mummy on the Orient Express)

An unidentified female singer aboard the Orient Express in space performed "Don't Stop Me Now" during a visit by the twelfth Doctor and Clara Oswald. It is not known whether she was an actual person or one of the hard light holograms created by Gus to populate the train. As such, her fate after the destruction of the train/spaceship is unknown.

Behind the scenes

 * A video showing Foxes' complete rendition of Don't Stop Me Now was released on the BBC website shortly after the transmission of Mummy on the Orient Express. It featured clips from the complete series 8 including episodes not yet broadcast at the time of its release such as TV: In the Forest of the Night and Flatline. The video was later included on the Series 8 DVD and Blu-ray box set. An alternate video, consisting solely of footage of Foxes performing the complete song, but without any cutaways, was also uploaded to YouTube but was not included in the box set.
