The Hitchiker's Guide to the Galaxy Radio Show Live!

Before it went truly intergalactic – before the squillion-selling "trilogy" of five books, before the comics, the computer games, the endless quoting, the TV series and the (decent) film version – Douglas Adams's wry sci-fi opus The Hitchhiker's Guide to the Galaxy started out as a fairly low-key Radio 4 series.

Thirty-four years on, the bulk of that first cast reassemble to scratch the HHGTTG itch. Among them, Simon Jones plays the hapless humanoid Arthur Dent (always having a bad day); Geoff McGivern returns as alien research bod Ford Prefect; and Stephen Moore voices the maniacally morose Marvin, the Paranoid Android.
