If you liked Hut 33, you may be interested in some other shows wot I wrote. One of them is Think the Unthinkable, the second series of which is currently being repeated on BBC7. Quite frequently. You can find the latest episode at here. You should be able to listen again later. This episodes features a company called 'Blue Herring' and contains one of my favourite exchanges with Daisy, splendidly played by the delightful Catherine Shepherd.
Incidentally, the first series of Think the Unthinkable is still available on CD from Amazon and other retailers. If you would Hut 33 to be similarly available please write to your MPs who will no doubt process your requests in the usual way and raise the matter in the House.
