Found at Huffington Post - 10:49 PM ET -- Mousavi's words on tape. This video, uploaded on YouTube today, purports to be of Mousavi's appearance at Saturday's rally. It seems more likely to be from an event earlier in the week, but either way, it is among the first post-election videos I've spotted where his words can be heard.

A Farsi-speaking reader tried to help translate but it was tough: "The crowd's chanting makes it so hard to pick out what he is saying. I can pick up a few word here and there, but not his full sentences. The gist is that he is among the martyrs... -- then the crowd chants. The crowd chanting is clear, but not Mousavi's speech." Let me know if you're able to pick up more.
