This is all a bit after the event, as it were, but I thought you might be interested even so.
I have just listened to a very interesting discussion about Siegfried Sassoon from a BBC podcast. It was first broadcast on 7 June 2007 and you will find it in this collection.

Beware though - there are some terrifically interesting-sounding programmes in here (including one each on the Odyssey and the Aeneid for those who took part in those discussions). I may have to give up sleep in order to find the time to listen to everything that I would like to hear!
