Back cover:

March 2003 sees the 25th anniversary of the first ever transmission of Douglas Adams's Hitchhiker's guide to the galaxy on BBC Radio 4. This celebratory edition of the scriptbook includes a previously unpublished Hitchhiker script; a new introduction by producer Georffrey Perkins; ans a Who's Who of all those involved in the radio series.

'It seemed to me, listening to radio comedy, that we hadn't progressed much beyond Door Slam A, Door Slam B, Footsteps on a Gravel Path and the odd Comic boing. . . I wanted Hitchhiker to sound like a rock album. I wanted the voices and the effects and the music to be so seamlessly orchestrated as to create a coherent sound picture of a whole other world...' Douglas Adams

So began the Hitchhiker phenomenon. The legendary BBC series did indeed push back the barriers of radio comedy, and in so doing won lavish praise from the critics and a variety of awards. It attracted a deluge of letters from a curious audience throughout the world and went on to spawn records, books, a stage production, a TV series, a computer adventure game and a towel.

Along with the new material in this edition, here are the twelve original radio scripts - Hitchhiker as it was written and exactly as it was broadcast for the very first time. Included are amendments and additions made during recordings and original notes on the writing and producing of the series by Adams and Perkins.

For perennial Hitchhiker fans and those new to Adams's comic genius, this updated and embellished edition of the scriptbook is essential reading.
