Just a side note to all you interns so you don't struggle with this like I did. Make sure that your input format is set to Full HTML rather than Filtered HTML if you're trying to embed a Flash player in your posting. It works much, much better that way!
Here is my intro recording, unedited. My challenge is going to be sounding coherent live so I challenged myself to see if I could record something which could go out as is.
A long time ago I used to do something which I think is peculiarly British and that is hospital radio (people joked that people felt worse rather than better after listening to hospital radio) so I have a little experience of live performance (apart from teaching of course!). I also did a couple of radio interviews, again a very long time ago bit the interesting thing was that the live interview went far better than the interview which I knew was being recorded where I ended up straying off the subject rather badly.
