That's the one I've got.
It's not "narrated" as such - those actors play different roles.
It has the end credits on every episode, so I'm assuming that it's a straight copy of the radio shows.
I have to say that the Brightonomicon is one of my favourite Rankin books, but they've left quite a bit out of the radio shows, mostly, I have to say, because it just wouldn't translate to audio - very much a visual thing.
Oh honestly. Now you've given me a terrible urge to shout:
I AM RUNE!
Oh, and David Warner's voice (especially if you're listening through headphones) is like melted chocolate!
I adore David Warner!
There's also a load of stuff at the end (like DVD extras) of interviews with Robert Rankin, and out-takes, etc.
Some are born great, some achieve greatness and some have greatness thrust upon them.
The rest of us are a bit crap.
