I think most people our age would be enthused by AM and Elton in particular, less so GnR who probably appeal more to those who were around for Appetite.
Roxy Music would appeal to barely any of us though.
I'm in that age range, and I'd see two of those 3 headliners. Nobody else that's being mentioned excites me more than the 3 here.
I'd see GnR and Elton, I've seen Arctic Monkeys enough times for one lifetime.
The main stage headliners barely matter to me anyway.
