25 years ago there was a play on the BBC radio called Hitchhikers guide to the Galaxy and it eventualy ended with 12 parts.
Now 25 years later, almost all of the original cast are back for 6 more new episodes that continue the adventures and you can catch the first episode here

But hurry because they only keep it up for a week before they go on to the next episode.
