Mná na h-Éireann who famously rocked the system, according to Mary Robinson, will be rocking Croke Park in their tens of thousands on Saturday night when Take That, the boy band turned to men's supergroup, hit town for the first major outdoor concert of the summer.
All 75,000 tickets sold out within hours of going on sale last October, a remarkable achievement for a band which originally split up in 1996 when Robbie Williams left to become a global superstar.
Many commentators believed the moment had passed for Take That when they reformed in 2005, but they are, if anything, more popular than in their original 1990s heyday. They have sold 1.1 million tickets for their Circus tour.
Promoters MCD estimate that 90 per cent of those who bought tickets for Saturday night will be women.
Many of the men's toilets will be turned into women's toilets to accommodate the gender imbalance.
"We're well used to it. We had the same situation for Westlife," said Sophie Ridley MCD event controller referring to Westlife's 10th anniversary concert at Croke Park last year.
Speaking at a press conference today to announce details of the concert on Saturday, Ms Ridley said the two stages, one behind the Canal End which extends the whole length of the pitch and the other near centre-field will be "one of the largest, if not the largest" ever assembled in this country.
Stadium director Peter McKenna, who saw the band in Sunderland last week, said: "There are a whole sequence of special effects and activities that it is going to make it a very spectacular show."
The weather for Saturday night is for warm and humid conditions with the chance of a shower and patrons are asked to dress accordingly.
Doors will open at 5pm. Hometown act The Script are on stage at 7.30pm followed by Take That at 8.30pm. The usual traffic restrictions around Croke Park will apply.
