The arena does look rather small so I wouldn't be surprised if the bigger arenas have a better production.I was thinking the same thing, but I suppose it is in the same vein as the Brighton or Bournemouth venues in that they are quite small so the design isn't really all there for an arena.
I read on ATRL that they would be doing all GW except for Clued Up and Love Me Or Leave Me, the older singles and a DC medley. We know for a fact that Word Up! didn't make the cut either, thank God.SETLIST STUFF
There's a medley with tracks from Beyonce & Bieber and they perform pretty much every Little Mix single. Black Magic is obviously the encore
