I guess there was a lot of emotion involved for Robert....I guess he felt a bit pressured as far as trying to re-create the "magic" of the 70s was concerned, when Zep was pretty much at their prime! Besides, as someone very rightly pointed out, a lot of time has passed by and so many things have changed and besides, one essential member of the band is missing and I guess to Robert, things will never be the same again! And I got this feeling from the article that Robert intended this whole Zep reunion show to be a "one-off" event and then pretty much part ways with Jimmy and JPJ and just move on!
