During his exile to Earth by the Time Lords, The Doctor relied upon the support of a paramilitary group known as UNIT to battle against alien invasions from outer space.
In celebration of this era of the programme, members of the cast and crew reunite to share their memories on a selection of classic episodes, including instalments of The Ambassadors of Death, The Mind of Evil, The Time Monster and Terror of the Zygons.
Moderated by actor, comedian and cult television enthusiast Toby Hadoke, this release features UNIT members Katy Manning (Jo Grant), John Levene (Sergeant Benton) and Richard Franklin (Captain Yates), as well as Margot Hayhoe (Assistant Floor Manager) and Michael Ferguson (Director).
These CDs can be enjoyed on their own or played in conjunction with the official BBC DVD release.
