For me this DVD is excellent

Love it.
Well, they don't try to make "show" but the sound and visualization is fantastic for me.
Cold?? I would say Harrison and Colin Edwin definitelly not. I know Wilson looks cold but he said in some interview that he is typical english man. Emotions are inside, it's just his personality. When you know his lyrics, I guess you would agree that he puts his emotions into words and music and not into how he looks on stage.
