I agree with most of the 4* and less comments.  While it was obviously a fun and unique performance the production failed.  The mix as captured on the VHS/DVD is uneven - it is evident artists are not "in the mix" although they can be seen playing.  Also, most troubling is the very poor time sync between video and audio.  Hands and mouths move way out-of-sync with the audio - it's a drag.
