We can only guess, but I don’t think it is the band. They are competent musicians who can learn new songs.I’m still genuinely wondering why the last string of shows all featured pretty much the same set list every time. Prior to that things had always been mixed up to a worthwhile or at least noticeable degree. Is it the band that can’t perform the songs or Morrissey being lazy and bland?
First signs of physical fatigue ( or whatever health issue he’s battling with)?
Fortunately, the setlist he kept repeating was solid, just missing the occasional surprises.
