Yes, am a bit of a Chris Morris enthusiast, I must admit.
I'd also recommend his brilliant CD of interviews with Peter Cook, who is in his role as Sir Arthur Streeb-Greebling called "Why Bother?", his strange, subversive "Blue Jam" CD and his short film "My Wrongs" all of which can be picked up fairly cheaply.
And for those who have a lot of time on their hands, there are some great downloads available on the Cook'd and Bom'd website of his early days on the radio.
