It seems that Stephen Fry will appear on the Late Late Show with Craig Ferguson on May 22. The format for the show will be the same as his previous visit. No audience, no Geoff, no Secretariat. Just Craig and Stephen discussing whatever they feel like discussing. The episode was filmed last week, but it's not due to air until May 22. I hate having to wait for stuff.
If you missed it the first time around you can catch it on Youtube.
