This first live version from the Tempest album is AUDIO ONLY. (well, it's a dark album, after all)
From the same show Mark Knopfler has some video (with sound) but a little bit incomplete:
In the meantime Guy Fletcher, playing keyboard in Mark's band and featured in the above short video, is just like the last year Dylan/Knopfler tour, keeping his tour diary on-line to give us all some inside information.
For the other information, like where to find the torrents, you have to go to the tour list Privateering In A Tempest We Will Go at WatchingTheRiverFlow
