First of all I was joking about the Beatles, I have seen the Stones with and without Bill Wyman but always with Ron Wood and it could be argued that without Brian Jones or even Mick Taylor in the early 70's that it really isn't the Stones. I never saw the Who with Keith Moon but I did see them without and compared to the video I have seen, there seemed to be something missing without Moon.
Now Back to Zeppelin, if it happens at all as rumor suggests, this would be a one off show for Desert Trip in Indio California. No Zeppelin tour just one show, if it happens at all. I agree with you without John Bonham its not Zeppelin, but drummers have been emulating John Bonham for decades and most likely if it happened Jason would be the drummer. Whoever the drummer would be, could play the drum parts exactly (but probably won't and you will always miss Bonham) as John Bonham played them, Page, Plant and JPJ could get any drummer they wanted for the gig. Its not like they are writing new material then you would definitely notice the absence of Bonham. If this show were to happen you can bet, Zeppelin fans will pay gobs of money and travel half way around the globe to see this show if it happens.
