"Following our successful experiment offering A Festival of Nine Lessons and Carols in surround sound at Christmas, we are now giving you the chance to hear a drama in surround sound. This time it will be available to download.

There are two versions of Private Peaceful to try, one is designed for use with normal surround sound speakers and the other gives an impression of listening on surround sound speakers using normal headphones."
(Play includes songs by Coope Boyes & Simpson)
