For the first time since the summer of 2019, there will be a live concert in Croke Park this weekend.
Pop superstar Ed Sheeran will take to the stage in the GAA's HQ on Saturday and Sunday to sold-out crowds.
It's Ed's second tour that has stopped off at Croker - the Englishman wowed 162,308 people while playing two gigs there in 2015.
However, with many of the attendees this weekend having had a long (Covid-enforced) break from live concerts, they may be out of sync with how things go on show day.
Luckily, Aiken Promotions, who are organising the gig, have put together a handy list of what things will look like over the weekend.
Here are some things to keep in mind if you are attending one of these dates:
Make sure your phone is charged
Your phone is where you will be able to display your digital ticket.
This is a digital ticket tour
If you haven't got it on you or it's dead, you may not be guaranteed entry.
Remember to download your tickets from your Ticketmaster account to your phone in advance of show day.
Check your digital tickets to be sure you are attending the correct venue on the correct date.
This one seems a bit obvious, but you would be surprised at how often it happens to people.
Just double check before you rock up to Croker this weekend.
Stage times and support acts
Gates will open at 4pm
The show starts at 6pm
Ed Sheeran on stage at 8pm
Show ends at 10.30pm
Denise Chaila & Maisie Peters will play as special guest on all Irish dates.
Make sure your bag is the correct size.
No bags larger than A4 size will be allowed into any of the venues on Ed's Irish tour.
Organisers are telling people to avoid bringing a bag unless it is totally necessary
You won't be allowed to queue early in the streets around Croke Park
The area directly around Ireland's largest stadium is full of houses and apartments, making it a residential area.
Ticket holders are being warned that "early queueing will not be permitted" - with organisers pleading with them to respect the privacy of the local community.
