I remember going to Longleat back in the day for various Doctor Who days and, every now and again, they would do a little mini-drama (there was one involving UNIT soldiers fighting Daleks or monsters or something (can't actually remember), so i can easily visualise what this mini Goodwood adventure would have been like.

Jon Pertwee has provided a voice over for Elisabeth Sladen to interact with as Sarah Jane and she races around the track in a car only to be confronted by some Daleks and - bizarrely - Aggedor.  As this is an audio only version, Aggedor does little more than roar.  I have no idea who is voicing the Daleks but it doesn't sound like any of the normal voice artists and does sound slightly off.

But Aggedor here is our saviour and presents the Daleks with a force to be reckoned with.  I listened to this to 100% Aggedor on the site's Character Tracker and it's a bit of an ignominious conclusion for this most noble of Royal Beasts.

Fun to hear Sarah mention Exxilon and Peladon though.
