Well, Tim Ireland and I did, on the Today programme broadcast of Thursday 22nd December. You can link to the Listen Again page here. Our interview clip is at 8:55. That should be up till Thursday 29th.
I'm also experimentally putting up a download link Download today5_bloggers_20051222.ram . Let me know if it works. If you can listen to the Listen Again links, you should be able to download and listen to the clip on your own machine, and it won't go away after Thursday.
