Intro: You may think the Gaztecs is money paid the government when purchasing petrol. In reality the Gaztecs is a group of space raiders led by General Grugger. And you may think Doctor Who is Doctor Who when he may be Meglos, who takes The Doctor's form because he's tired of being a cactus. And you make think this is WTTW, Chicago. On that count you're right.

Outro: Next week, The Doctor and Romana meet the starliners who are not a vocal group. They will also encounter the marsh creatures who are just what their name implies. And the young outlier named Adric who will decide to stick around for a while. Be with us next Sunday at 11 and be prepared to turn "Full Circle." [source: ChicagoEpguides]
