There's an up and coming band coming on the stage now and playing for you, they’re called...U2.

U2 played a nine song set in total. In this footage shot for RTÉ News the band are playing ‘Sunday Bloody Sunday’. A number of fans close to the stage pass out during the performance and have to be taken to a nearby hospital.
