Notes[[edit] | [edit source]]

This audio drama was recorded on 15 and 16 July 2008 at The Moat Studios.
In the original play on which the audio story is based, Trevor Martin's Doctor regenerated from Jon Pertwee's Third Doctor, by means of having Martin obscure his face under a wig and removing it as the Doctor regenerated. In this version, however, the previous Doctor is heard with the voice of Nicholas Briggs, with no resemblance to Pertwee's voice.
This story was originally released on CD. It is now available as a download, as well as to stream on Spotify.
Nicholas Briggs portrayed another Previous Doctor in AUDIO: Exile.
Trevor Martin's Doctor is pictured differently from his appearance in a stageplay, most notably - his hair is a lot shorter.

For the purposes of this list, a "regeneration story" is one in which a regeneration is actually and initially depicted. For this reason The War Games is not included below, even though it is commonly thought of as a "regeneration story". It doesn't actually include a clear scene of regeneration, and the preponderance of stories in other media confirms that the Second Doctor did not regenerate at the end of it.
Additionally, immediate post-regeneration stories, like the 2005 Children in Need Special Born Again — and ones like Castrovalva, where the regeneration sequence was replayed — are not included.

Post-regeneration stories

For the purposes of this list, a "post-regeneration story" is one in which the after-effects of a regeneration is actually and initially depicted and the Time Lord fully settles into their new body. For this reason, Rose is not included below, even though it is commonly thought of as a "post-regeneration story". It doesn't actually include a clear scene of regeneration, and the preponderance of stories in other media confirm that the Ninth Doctor has not immediately regenerated prior to the story.
