From the BBC. Alternate headline: "Irish Bafflingly Ungrateful for Being Spared Garth Brooks Concerts."

GAA director general Paraic Duffy told the Dáil committee on Wednesday that he was happy to allow Croke Park to be used, in spite of complaints from some residents, because the Garth Brooks gigs had become "an extraordinary and utterly unpredictable social phenomenon".

He said they were more than just concerts, they had become a "national event".

I agree—a Garth Brooks concert being a national event is both extraordinary and unpredictable.
