Opera fiends who have been storming the National Concert Hall for news of Jose Cura's next Dublin performance will be relieved to hear that tickets will be on sale from next Wednesday at HMV. On Saturday March 14th the Argentinian tenor (right) will be joined, in the RDS Main Hall, by the National Symphony Orchestra, conducted by Alexander Anissimov and a combined choir of 200 for an "Opera Extravaganza".
