An elaborate April Fools' Day prank with U2 tribute band 'U2opia' fooling U2 fans in Cork. 'U2opia' perform live from the roof of a supermarket in Blackpool, Cork, gathering a crowd on the street below who believe them to be the real deal.

The prank was set up by Red FM. In the days leading up to April Fools' Day they broadcast that U2 was touring around Ireland at secret locations to promote their new album launch. 

Also in the news on April Fools' Day was a spoof article about electronic tagging that appeared in The Irish Times. The story got the politicians talking in Dáil Éireann and there were plenty of other pranks at home and abroad.

Hugh Linehan of The Irish Times comments on the placement of April Fool stories in newspapers.
