U2 fans have expressed fury after it emerged the three Croke Park concerts in Dublin for its 360 tour will not be fully "in the round" as concerts at other venues around the world will be. Fans been posting comments on twitter."Pretty annoyed to find out were only getting 270 of the stage," The "claw" stage at the centrepiece of the show wowed fans in Barcelona at its launch last week and allowed the band to effectively play to all sides of the all-seated Nou Camp stadium. The stage was situated at one end of the stadium in Barcelona, and will be in the same position at Croke Park, with Hill 16 as a backdrop. However, no seats will be fitted on the Hill and no tickets have been sold for the famous terrace -- which means that the band will effectively be playing to 270 degrees of the Jones Road venue. "There is no reason why it can't be in the middle." A seating chart for the concerts -- which take place on the 24th, 25th and 27th of this month -- shows that all stands at Croke Park will be filled, and there will be space for fans on the pitch. However, there will be no standing space behind the stage, as it backs on to the Hill.
