Wilco's first night in Sydney was very short because of an apparent miscommunication about when the set had to end. To make up for this (and the cameras that were required to film the second night - although I can't see how that hampered the show) the band have offered ticket holders downloads of both shows. It seems that these are already circulating freely, so I'm assuming it's OK to put these up.
The second night was also on youtube, although it doesn't seem to be available right now, hopefully because they're sorting out the fact it's horribly out of sync. [Update: yup, someone has fixed it up - http://www.youtube.com/watch?v=7HHW217cpKA]
