Well the first half of the things a streamin on the hinterVeb http://www.youtube.com/watch?v=FwnXHxjp-Qw

If you like disc 1, it's probably worth investing in the entire thing.

HA!

28:33 into that Video. The sound Jimmy supposedly made is a definite overdub.
Just sayin'  It's not actually possible to play a single stable closed chord and do a detuned slide at the same time. You can hear the overdub perfectly in fact. Now it could have been a live overdub on the night so maybe no studio time went into this BUT, if you're already booking a studio for post-production you might as well spruce up the tracks with some overdubs. We all know how "re-master" happy JP is and how many god damned times he's redone the old classics, it's not a huge jump in my mind for him to over-dub Celebration Day.

Zep were a band who like Pink Floyd and the Beatles used the studio as an instrument in it's own right, don't see that as a bad thing personally, the music is what matters, but there's definitely some work done here in my (professional) opinion one way or the other.

It's just impossible to tell if the work was done in the postproduction suite or live on the night using pre-recorded overdubs.

None of this tarnishes the result in my mind. It's excellent music and these are excellent versions of some monolithic songs.

Me too Jason. Me too.

This is the best thing GNR has done post '91.
Bringing Izzy out for a few shows is an excellent treat for the fans of the old band too.
