Abba in Space?

Blake's 7 ran for four years on BBC 1 from 1978 to 1981.

Blake and his gang of rebels cruised space in their hugely advanced space craft, the Liberator. They were fighting the evil federation, run by new romantic diva Servalan (Jacqueline Pearce).

Blake's crew looked rather more like Abba, with their unflattering beige combinations of nylon and leather, and an endless supply of perming hairspray. Blake himself left after two years, leaving his rebels in the hands of Shakespearean schemer Avon (Paul Darrow).

The show aimed to be a grittily realistic TV answer to Star Wars, only on Doctor Who's budget. The result is controversially stylised, with bold use of Colour Separation Overlay, bright lighting and big hair.

In the episode Moloch we see Avon pursuing Servalan to the edge of the universe. She's discovered a corrupt federation colony, who hold the key to the ultimate lifeform - the mysterious Moloch.
