The audio recording for my PyCon 2005 talk is available now. The pre-slides-coming-back stuff wasn't as bad as I'd feared, in fact, I prefer it to the stuff after the slides appearing, especially as there's a lot of dead air where I'm wrestling with the computer rather than talking to the audience.
There's nothing recorded from the beginning to explain, but the laptop crashed just as I was getting up to speak. The jokes didn't go as well as I recalled, have to work on those.
Thanks to the volunteers who did the recordings!
