Shoppers in Dundrum Town Centre in south Dublin were surprised this morning by a large-scale and apparently spontaneous choral performance of the Hallelujah chorus from Handel’s Messiah. The twenty choirs which took part were positioned on three levels around the shopping centre with the conductor stationed on the top floor outside Frangos foodstore. The flashmob-style event occured at 12.40 pm and marked the culmination of RTE’s Big Music week. Aproximately 400 singers took part and were applauded by customers keen to join in the fun.
