he most useful advice ever given, 'Don't panic', can be found within the Hitch-Hiker's Guide to the Galaxy. The day aliens decide to demolish the Earth to make way for a hyperspace bypass is the day when Arthur Dent realises the futility of such advice.

The story begins when Arthur, not really your average man-in-the-street, finds that his planet is suddenly destroyed around him, and the great hitch-hike begins... Starring Peter Jones as The Book, Simon Jones as Arthur Dent and Geoffrey McGivern as Ford Prefect, this is the first Douglas Adams' legendary radio series.
