Ed Sheeran is still set to play in Philadelphia on Saturday night despite all his support acts and his backing band having quit.
It comes after the rapper Macklemore was dropped for making pro-Palestinian comments on stage.
Some sources say Sheeran and his management have discussed cancelling the tour, which could cost the singer millions.
Our US Correspondent Dan Rivers visited Philadelphia close to where the gig is taking place to speak to fans and protestors.
