Zeppelin are a band who you cannot really put down, as they know if they went on stage and did a poor gig, they'd still go down well with the crowd. I couldn't imagine Pagey getting heckled and boooeyd off after dropping a few bum notes. Me brother went to see them in 1979 at the first Knebworth gig he was a big fan and only 16 at the time, but my parents let him go to the gig. Sadly i was 14 and not 'gig ready'

. When me bro came home he'd had a great time with his pals etc. But Zeppelin didn't live up to his expectations, they didn't do a very good gig. He said Todd Rundgren was awesome and Jim Steinman came on stage and did the 'Meatloaf Bat out of hell' guitar solo with Todd. Which sounded awesome. The Knebworth gig was videod and it took years to get officially released and when it did, it had been tweaked and overdubbed. With the worst songs being missing from the package. I heard an audio bootleg from the show at the time and it did sound rough and sloppy.
Fast forward to the last gig LZ played at the o2 arena in London. One of my pals was hyped up for the gig and it was the same story. An overpriced sold out gig with support bands who made Zeppelin look like a poor headlining band.
One Pagey show that sticks in my mind was the gig he did with Robert Plant in 1991 at Knebworth. Pagey came on to do a couple of Zep numbers and he sounded like a cat being tortured. After Plant had done an amazing set with his band 'Tall Cool One' 'Liars Dance' 'Tie dye on the highway' great tracks. If one player isn't up to scratch its normaly a knock on effect for the rest of the band to go downhill. The press being the first ones to forget how they've done 1000's of mint shows but they'll always be remembered for that handful of gigs that the band would gladly forget.
