"Don't Stop Me Now" was a song performed by a singer on board the space-faring Orient Express. (TV: Mummy on the Orient Express)
A recording of this performance was obtained by Clara Oswald and was playing on either a radio or a jukebox in her TARDIS when she was briefly reunited with the Twelfth Doctor. (TV: Hell Bent)
Behind the scenes[]
This version of "Don't Stop Me Now" is sung by Foxes, and specifically recorded for Doctor Who. The song is a variation upon Queen's original composition but is not attributed to the group in Mummy on the Orient Express.
Due to the way the soundtrack is edited, it is not possible to confirm whether the song heard in Clara's TARDIS is playing on the visible jukebox or over a speaker system in the "diner".
