Plans to build the tallest tower in Ireland were cancelled today, to the disappointment of U2.  The top floors of the building in Dublin were to be a recording studio for the famous Irish band. Unfortunately, with the economic downturn, especially in real estate issues, the building was considered ill-advised at this time. They plan to go back into building the tower in the next year or so, but they will have to renegotiate with various people to do so.  The building was designed by architect Norman Foster and was to be triangular.  U2 fans everywhere will have to wait, then, to get their U2 tower.
