Comedy on BBC Radio 4 generates a lot of discussion in the Feedback inbox, and this year's been no different, especially after the introduction of a new raft of comedy commissions over the last twelve months. Andrea Catherwood talks to to Julia McKenzie, Commissioning Editor for Comedy and Entertainment, and Jon Holmes, comedian and creator of one of those new commissions, The Naked Week - and they respond to listener comments and critiques. And as Christmas approaches, we go behind the scenes in King's College Chapel as preparations take place for Radio 4's annual Christmas Eve broadcast of the Festival of Nine Lessons and Carols.
