From my fave Zep bootleg, cover of Buffalo Springfield's What It's Worth

Yep, you read right... Zeppelin doing a magnificent job of the Buffalos... Blueberry Hill bootleg is top of my pile of Zep bootlegs... There's a second version as well...

I prime example of how you can play out of time and out of tune... but its rock and it doesn't matter. The music was passionate and reflected the mood of the moment.

Exactly... the tune popped up in the middle of Communication Breakdown as part of one of their mid-song medleys, barely planned. I have to agree though, a lot of their concerts were unlistenable, particularly latter day, because of sloppiness. But, here, the energy wins out.
Have a look at Led Zeppelin DVD (double box set) - AWESOME performances...
