All five Garth Brooks concerts have been called off.
Aiken Promotions says it has exhausted all avenues regarding the staging of the events at Croke Park - and no concerts will now be taking place.
The performances were due to take place later this month.
Aiken Promotions - who says its very disappointed for the 400,000 fans - says the ticket return process will be outlined tomorrow.
Ticketmaster says its working on a plan to make the cancellation process as simple and convenient as possible.
However the company says the scale of the operation is unprecedented in the Irish entertainment industry - and its appealing to customers to be patient while it finalises the plan.
