I find this a bit odd. I had no issues with the Rolling Stones concert last year. There was an orderly queue to get in which took about 20 to 30 mins bit that's was about it.
Saw a video on Twitter of this kid in Northern Ireland called Mohammed. He is basically a refugee from Syria. But has been in NI for so long that he has developed a Jim McDonald accent! So the children of these immigrants become British surely?
