Hmm, I may actually go see this. I’ve never been a big fan of Zep, even though (come to think of it) that I have every one of their legit albums (I’m not counting “The New Yardbirds”, since that one was pulled almost immediately, and I’ve only seen one copy of that, ever; the tracks were either similar to or had a lot of overlap with or were identical with the material on the first Zep)... ;’)
I remember the days when you could walk into certain “underground” or “hip” record stores in LA and NYC and buy bootleg albums or cassettes that the clerks kept behind the counter. I picked up some good Zep bootlegs that way. Didn’t matter at the time that the quality was poor. It was the next best thing for actually being at their concerts.
