A little bit of background: In 2005, BBC7 broadcast several Eighth Doctor Big Finish audio plays. Because the new series with the Ninth Doctor had started only a few months before, two radio spots were recorded to help listeners understand the difference between the two Doctors. One is a factual overview of the Time Lords and regeneration. This one features Eight explaining who he is to a somewhat unintelligible alien who only knows his next incarnation. It’s a fun little introductory clip.
