Firstly, just want to clarify my "pretending it never happened" comment was a sly jab at Priest, who like to pretend the Ripper era never happened. For all the shit (undeservedly) Maiden got for the Blaze-era, they stand by them, which I respect immensely.
My idea of a perfect "final tour" for Maiden would be something akin to Metallica's 30th Anniversary shows, just maybe not as broad with the guest appearances. Have Blaze and Paul come back for a song or two (I like Diesel's idea of "Wrathchild", might make people actually look forward to hearing it), maybe even Dennis Straton. I wouldn't hope or expect Maiden to bring back everyone who's ever been involved with the band ever, but those three have been a very important part of their history and, perhaps with the exception of Den, still maintain huge appreciation from fans.
I don't consider Maiden a "big happy family", but as far as I'm aware, they've never shown any animosity towards Blaze, Den or even Paul - despite all the shit he gives them. I maintain a vain hope that Paul would be mature enough to let by gones be by gones for the sake of one final "Hurrah".
