The financial dimension always plays into it, but because the endeavour is so expensive in general, I don't see that as a likelihood. It would still likely be needing at least two of those superstars to drop prices or have a festival affiliation - see; Neil Young.
Still such a bizarre saga, that one.
Interesting, as I think it is his first "great" album, even if there isn't quite the larger depth of out-and-out bangers yet.
I think he's had a few issues picking his choices live too. He hasn't quite nailed the specifics of picking the best live songs sometimes.
From comments Dave Murray has said this week, about Maiden packing it in before they fall apart, I genuinely think this will be the last tour - or at least on this level. Wouldn't be surprised if it extends through 2027, albeit while only plotted for 2026 as it stands, and then they call it quits live.
I do love me some Biffy Clyro too, but not sure they'll get the nod again unless they are struggling. (I do love advance planning like this though.)
