The Hitch Hiker's Guide To The Galaxy(tonight, 6:30pm, Radio 4): I remember listening to the last series of the Hitch Hiker's Guide To The Galaxy tucked up in bed after a hard day at school in the year before I took my O levels. I still have the souvenir Radio Times with a giant celestial thumb on the front cover (I must check eBay to see if it's worth anything), from which I note that evening I also enjoyed Blake's 7, the Goodies and a LyndaCarter Variety Special. But it was Douglas Adams' outstandingly original flight of fancy that captured my imagination, and I'm sure will again today after a hiatus of almost 25 years. That quarter-century gap has been plugged by a TV series, more books, a commemorative towel, an interactive adventure game, rumours of a film and the tragic death of the author, but it'll be great to have the third series back tonight along with most of the original cast. While we wait, here are some links to remind us all how good it used to be. 42 of them, of course.
