I haven't listened yet to the Wireless Theatre stuff yet, but I come bringing news!
The Scarifyers website has been updated to include "The Horror of Loch Ness- featuring the story synopsis and fantastic CD cover art by Garen Ewing.
Its page is here: http://www.cosmichobo.com/scarifyers/The-Horror-of-Loch-Ness/
As well as the regular cast, it also stars the late Philip Madoc- who sadly died a few weeks ago. He was Brother Cadfael in the BBC radio plays, and featured many times in the old Doctor Who series- perhaps most memorably as Solon in "The Brain of Morbius."
He also memorably guest starred in Dads Army as the U-boat captain in one of its funniest and most famous scenes.
Also, They have started recording the next Scarifyers story "The Thirteen Hallows" and it features Gareth-David-Lloyd who played self confessed Tintin fan Ianto Jones in Torchwood. http://www.cosmichobo.com/news/
Just to let you know Jock- I've started listening to Jago and Litefoot- and yes, it is excellent! Really happy for Christopher Benjamin, Trevor Baxter, and all involved.
I've found that you can also get them as individual stories on itunes which suits me more as I already have an account there.
