The audio soundtrack survives. The BBC has given it three commercial releases: first, on cassette release with narration by Tom Baker; second, on CD with narration by Anneke Wills; and third, on MP3-CD for the 'Doctor Who: Reconstructed' range, again narrated by Wills. This release also includes a bonus slideshow for PC/Apple Mac users, merging the soundtrack with tele-snaps. The Wills-narrated soundtrack was also released in a collector's tin called "Doctor Who: Daleks", along with the soundtrack to "The Evil of the Daleks" and a bonus disc featuring "My Life as a Dalek", a story presented by Mark Gatiss and discussing the history of the Daleks.
