Here's the thing about Def Leppard, though. I got in with TAC. My first time seeing them was the Pyromania tour as well (they KILLED it. I mean KILLED it.) I'm a "High And Dry" guy all the way, though I do like the next two better than most (I actually like Hysteria better than Pyromania).
But I saw them open for Kiss a couple years ago, and it's almost entirely a hits set at this point. And here's the thing: it's GOOD. They've been starting their shows by playing "Won't Get Fooled Again" by the Who, then finish the song themselves live, which is cool, and most of the Hysteria songs (the bulk of the set) are done really well. It's five really good musicians playing fairly complicated material and yet it rocks. No, I wouldn't pay $150 to see them, but if I got a $50 ticket from StubHub or something? There are worse nights out, let me tell you.
Cram, I'm with you; British Lion does little for me. It reminds me of bad ASAP (which was Adrian's gig after he left Maiden in... '88 or so). If I go, it's purely to see Steve Harris in the toilet. Erm... you know what I mean.
(And for the record, Vivian was playing the Dio material he did with... Dio.)
There is zero zoom on this. It was actually awkward because he was eye level and only about a foot and a half away:
