Garthmania has returned to country music. Superstar Garth Brooks has sold out two more comeback shows, again just hours after tickets went on sale.

Brooks announced Monday (Feb. 3) that he was adding a fourth show to his Comeback Special concert series, which will take place at Croke Park in Dublin, Ireland in July. When tickets for that show sold out immediately Thursday morning (Feb. 6), promoters added a fifth date, which also quickly sold out. Brooks has now sold a total of 400,000 tickets to the five shows, which will run from July 25-29, 2014.

Brooks has had his eye on Croke Park since he played there in 1997, while the stadium was under construction.

“Before we go back on tour in the fall of 2014, I want to challenge myself, the band and crew,” he said when he announced the new dates. “In ’97, we were lucky enough to play Croke Park, the stadium was under construction. 130,000-plus of some of the greatest fans in the world. I was quoted then as saying, ‘When this stadium is finished, I would love to come back and try to fill it again…this time to the brink’ -- and we’re back to do just that.”

The singer has yet to announce specific dates for his upcoming tour, which he revealed in a surprise announcement on ‘Good Morning America’ in December. That followed closely on the heels of his ‘Blame It All On My Roots‘ box set, which dominated the holiday season in sales and spawned a top-rated television special, ‘Garth Brooks: Live From Las Vegas.’

The country superstar, who is a member of both the Country Music Hall of Fame and the Nashville Songwriters Hall of Fame, has stated that the comeback tour will last three years. He also recently released a new single titled ‘The Call’ with his wife, Trisha Yearwood.
