In short:
Pop superstar Ed Sheeran has returned to the stage after he became embroiled in a controversy that saw four supporting acts quit his Loop Tour.
Rapper Macklemore was dropped from the tour after owners of stadiums hosting upcoming shows objected to his pro-Palestinian comments on stage, prompting other supporting acts to quit.
Pro-Palestinian protesters have gathered outside the Philadelphia stadium where Sheeran is performing.
He only got emotional when he was thanking people for still showing up, because that’s what he cares about.
