This charming lady was called Zelda - an alien from Gerry Anderson's 1980s Sunday teatime series, Terrahawks. There was a game of noughts and crosses mixed up in the credits and, sat there, more often than not recovering from a clanging hangover, a legacy from the night before, I used to love it. Anybody else remember it? This 1983 edition of Look-In also offered us Knight Rider, Dangermouse, Tracey Ullman and Abba. Good, eh?
