Apart from the R Dawkins and C Hitchens files, there's an interesting talk by ex-Labour MP Tony Benn. For those who don't know him, he's an elderly gentleman (now in his 80s) who has endured many UK governments, both left and right, but who has always stayed true to his left-wing principals. In this recording, he speaks briefly about his religious views, his childhood meeting with Gandhi and the monarchy.
