REACH for your earplugs because Jedwardmania is sweeping the country after twin brothers John and Edward Grimes kicked off their sold-out Irish tour in Castlebar last night.
When tickets for the first night's show in the town's Royal Theatre went on sale in January, they sold out in nine minutes, and from what the Irish Independent saw last night Jedwardmania is right up there with Beatlemania.
Fans besieged the venue yesterday, among them Honor Clune (15) and Sinead Cawley, both from Castlebar, and Lauren Murphy (15) and Niamh Medshaw (15) from Westport.
Ears pressed to the fire exit doors, they craned their necks to hear their heroes sound-checking before the show.
"Oh my God, we can hear them singing," they shrieked.
Standing nearby, four more fans, Cathy Egan (15), Leanne Walsh (14), Siobhan Judge (15) and Lauren Murphy (15), all from Ballina, had queued for three hours in the snow for tickets when they went on sale. " Jedward are so nice and funny and they love their fans," said Cathy.
Proof of this came at 6pm when a side door opened and Jedward emerged to greet their followers. The 'meet and greet' lasted just 30 seconds before the twins had to be rescued after disappearing into a sea of screaming teenagers.
Last night wasn't only the first night of Jedward's Irish tour, it was their first proper full-length gig, featuring 18 songs.
"Our manager, Louis Walsh, picked the songs. They're the kind that even if you don't know their names, everybody knows them," said John.
These include M's 'Pop Music', Van Halen's 'Jump' and even the Bay City Rollers's hit 'Bye Bye Baby'.
What had been seen earlier in the day was nothing compared to the pandemonium that ensued when Jedward entered the auditorium at 8.30pm, walking through the crowd like champion boxers with their names on the back of their dressing gowns, before bounding onstage.
It's true, John and Edward speak rather than sing, and bounce instead of dance but it's hard to look away from their stage performance.
It's all about entertainment and the Lucan boys certainly provide it. After the weeks on 'The X Factor', where they endured taunts from the judges and audience, there was nothing but love from the crowd in Castlebar.
There were plenty of costume changes, including the boys donning matching red leather jackets for Britney Spears's 'Oops, I Did it Again and backpacks for the 'Ghostbusters' theme. The pair perform without a backing band, using the space on stage to turn cartwheels and move around.
Among the 2000 screaming teenagers in Mayo were two of the boys' biggest fans: parents John and Susannah Grimes.
The boys play Leisureland in Galway tonight.
