Some thoughts on the set and the PLAY CLASSICS!!! thing:
While I'd gladly replace one or two songs from the "obvious classics" section with something more interesting, I have to say that they've really managed to get these songs very good; actually, most of the performances are the best ones for many years. For example, I just listened to The Trooper from the Stockholm gig; Bruce hasn't put this much effort to the delivery for ages. Or actually, there were some pretty awesome performances during TBOS tour too, so whatever they've talked about "every show being kinda sacred nowadays" and being "more excited about performing when they get older" etc. seems to be true to some extenct. However, Fear of the Dark is perhaps the most notable example of this: Bruce and co. really blew a lot of new life into it. The slower, heavier approach combined with Bruce's intense vocal delivery really makes the song work very well now, in contrast to what it has been for like... past decade or something: effective live song with a strong crowd reaction, yes, but somewhat dragging.
And then there's The Evil That Men Do; the slower, heavier approach worked very well in Maiden England tour too and brought it a bit closer to the original album version, unlike the faster, more aggressive (equally awesome, though) performances of it they favoured until AMOLAD tour, if I recall correctly.
Some of those songs are overplayed, yes, and I've always been eager for a change when it comes to their inclusion to the set(s), but when the execution is as strong as it is now, they work very well! It's just if they've replaced some of those songs during a couple of past tours with something else (example: 2MTM in TFF '11 or ME tours and FOTD on both previous history tours) their inclusion would have had much warmer "welcome back" effect even among us hardcore fans. While they have to play most of the big favourites time after another, I would have liked to see just a bit more variation with the choices. TBOS tour was a step to the right direction though, with Powerslave, Children of the Damned and Wasted Years. I hope they'll keep it like that. Something like Phantom of the Opera wouldn't hurt on next album tour etc. You get the point.
