In general, it is difficult to add something to the tracklist. Two DVDs of rare Led Zeppelin live recordings prior to 1972. So many variants of dazed and confused execution are unlikely to be found anywhere else :). Of course, somewhere the video is not of very good quality, but I recommend watching it for fans and collectors.
