I remember back in 1987 or 88 they did the Atlantic Records 40th anniversary show with Jason Bonham on drums. He wasn't the problem and neither was John Paul Jones.

Plant should not reach for the high notes anymore. He fell horribly flat during the finale of Whole Lotta Love and Page looked like he was going to fall over and sounded like he had never played a guitar in his life. This saddened me because Page remains to this day one of my biggest guitar influences. Coincidentally, his Otrider album came out around the same time and featured some pretty sweet [studio] licks.

If they could guarantee a subdued Plant and a sober Page it might be a passable concert, but I would rather not see it happen. Gonna disagree with JimB; I don't think they went out on top at all. Presence and In Through the Outdoor pale in comparison to Physical Graffiti and even Song Remains the Same. Don't even get me started on Coda (okay it was released after Bonham died, but still.) As much as I love Zeppelin, I say let dead dogs lie. No good can come of this.
