I just hope she doesn't do
loads of costume changes. Well, it probably won't matter since she did last time at MIA, but when she did V Fest in the UK in 2013 with TMCSWT she was literally dragged for leaving the stage almost 10 times to change, because festivals are usually an all-in-one performance ala Glastonbury
edit: yeah, no costume changes. The Sweet Dreams comments above made me re-watch it and reminded me that Glasto with it's one outfit is still her best concert ever
