Sort-of-tangentially related; I remember watching a doc about Iron Maiden doing a world tour in ~2008 or so, where they were playing a setlist very close to that of their huge 1985 world tour, where they were asked about doing “only a greatest hits tour” with very little new material.

$BandMember replied something like: “This is stuff off our biggest-selling albums which we’ve not played live for donkeys’ years. There were loads of people in the audience last night who weren’t even born the last time we played $Track live in this country – we’ve said from the first tour publicity that this is what we’re going to be playing, and I’m pretty sure lots of people are here entirely because we’re playing this stuff”

I don’t really do gigs (I’m much happier at home with a comfy chair and a decent recording) but I can absolutely agree that, if you do enjoy gigs, it’s far more about who’s playing, what they’re playing, and how good a job they’re doing of playing it. The age of the material and the band is probably a bit further down the criteria for enjoyment…
