Singer (Mummy on the Orient Express)

A female singer aboard the Orient Express in space performed "Don't Stop Me Now" during a visit by the Twelfth Doctor and Clara Oswald. She was actually a hologram to make up the numbers of the passengers and vanished shortly after. (TV: Mummy on the Orient Express)

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 In the Forest of the Night and Dark Water. 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.
