Videos comprising the full hour discussion session with Bob at Dance in the Desert 2012 have been put up by the videographer who I only know by his online handle: Dance Ranger. They don't come up with YouTube searches yet, and for some reason also don't show up if you look at Dance Ranger's YouTube page. So here are the links.
