This flash mob chorus in Ireland will make your heart swell.iStock

It's a beautiful moment a number of Dubliners will never forget. A Dublin shopping center was the scene of a joyous flash mob attack in 2011, as hundreds of singers from choirs serenaded shocked shoppers.

The mass rendition of the Hallelujah Chorus was the grand finale of a Big Music Week organised by Ireland’s national radio station RTE.

Just after noon, hundreds of people from choirs all over the country joined together to surprise shoppers.

Organizers described it as a ‘great success’ while the stunned shoppers said they were delighted with the impromptu gig.
