Fans of Julio Iglesias were devastated at the performance the Spanish singing legend gave at The O2 in Dublin.

The 70-year-old Latino crooner has sold more than 120 million records worldwide in 14 different languages but his global spark was missing for many at last night’s show.

Life-long fan Grainne Hayes contacted RTE Liveline show this afternoon to speak of her disappointment in the performance.

“He indulged himself in Spanish songs we never heard of. And when it got to ‘All the girls we love’, I wouldn’t have known it if it wasn’t for the band melody,” she complained.

“He mucked it up completely,” she told presenter Joe Duffy, describing a darkened stage that many of the older audience found it difficult to see the main act they had paid over €60 for.

But despite people leaving mid performance – “I thought they were going to the bathroom but they weren’t coming back” – organiser and promoter Pat Egan said that attendees would not be getting their money back.

Mr Egan, who himself complained to the sound engineers about the quality, said “it was not the performance I would have expected from an artist of that calibre disappointed in the performance.”

“I think Julio might have thought he was in Mexico,” he added.

However, he maintained that it is his job “to sell seats” and “after that, the responsibility of the performance falls on the artist”.

Another disgruntled Irish punter Paddy rang in to the show to ‘talk to Joe’ to say that last night’s performance was “the worst concert I ever attended” and the singer “could hardly get on stage”.

“Our country has become a pension fund for singers. You don’t pick a football player who isn’t 100pc fit so why employ a singer that is not even 20pc fit?

“I went to Tina Turner and Bruce Springsteen and they could play three hours without stopping.”

The criticism of Julio Iglesias' performance in Dublin follows a harsh review in the Daily Telegraph of the artist's London performance at the Royal Albert Hall.

Meanwhile, callers rang in to commend 69-year-old Christy Moore on a fantastic performance in Galway last night.

"Christy is on a different plane," one fan told Liveline.
