Where to find the iOS development session videos from Brad Larson?

Someone told me that Brad Larson has published good iOS development videos on iTunes U. He said there are supposed to be two classes similar like those from Stanfo开发者_JAVA技巧rd.

The terribly bad search UI of iTunes seems to lock me out of those videos. I can't find them. Not even when I search for Madison or Brad Larson. I'm also logged in while searching...

Can anyone point me into the right direction? Maybe Brad Larson himself? ;-)

Link to iTunes video can be found in Brad Larson's profile which, in turn, can be found at the very top of top iphone answerers ;)

And, in my opinion, those videos are not good - they are very good :)
