Tickets for the Friends In Low Places singer's first two dates went on sale yesterday morning. These gigs were planned for 9 and 10 September.
An extra date was added within 40 minutes of the tickets going up for sale. A further two dates were then added at 10 am. These shows will take place on the 16 and 17 of September next year.
All five dates at GAA's Headquarters sold out due to high demand.
