Over 7,000 tourists are expected to fly, sail and drive into Dublin this weekend to see Irish rockers The Script play Croke Park.
The Dublin band looks set to play in front of a sold-out crowd in the stadium on Saturday, with 7,500 of the 80,000 tickets sold purchased abroad.
Concert promoters MCD revealed that while 50pc of the ticket sales were based in the Dublin area, there was also a large interest from outside of Ireland.
Fans from as far away as Japan, South Africa and Afghanistan have snapped up tickets for the band's biggest headlining gig.
"I think that people are actually coming home to see The Script because it's a huge celebration and it's on their home turf," Justin Green from concert promoters MCD said.
The promoters also revealed that along with alcohol, umbrellas and recording devices, selfie sticks have been banned from the gig.
"They can become like missiles and they also get in the way of other people's enjoyment.
"If you have a stick up in the air it's like an umbrella and you're trying to look at the gig through a stick," event controller Eamonn Fox said.
"It's okay taking pictures but there's no need for the camera to be up there blocking the view for everyone else," he added.
The band, who are only the third Irish act to sell out Croke Park after U2 and Westlife, will be the first performers to stream their concert from the venue.
The Script teamed up with site Livestream to broadcast the gig live from their website to fans worldwide, a move which MCD said they support.
"It's the atmosphere you're paying for.
"It's the experience of being there in that crowd that people will never forget," Mr Fox said.
Although the gig is a sell-out with 80,000 fans expected, MCD say there are still a limited number of tickets available for the event on Ticketmaster.
Doors open in Croke Park at 5.30pm, with the first support act, The Wailers, taking to the stage an hour later at 6.30pm and Pharrell Williams is scheduled to perform at 7pm.
Concert-goers are being urged to ditch their cars and walk to the stadium or use public transport.
Dublin Bus has a number of routes that run close to Croke Park and Iarnrod Eireann will be bringing extra trains into Drumcondra Station for those coming from outside of the capital.
Bus Eireann will also be running additional services for the concert.
