The two men have mops, they have big yellow, industrial buckets on wheels, they are dressed in black. They're kind of funky looking. It's dark, it's a night-club, there is the slow build of an unrelenting beat.
They begin to mop. Would they, by any chance, be part of a floor-show that is about to start? At all, at all? Surely Mitch Kavanagh from Ballsbridge, and John Lee, from Liao Ning in north China, are getting ready to dance. Helloooo. We're mopping the floor, they explain. They would have been really good, too.
A party is about to kick off in Tomato, a new night-club in the basement of Harcourt Hotel. Invited to the party are Katie Tyrell, a veterinary student from Trim, Co Meath, and her boyfriend Jonny Greene, a tillage farmer from Athy, Co Kildare. They're about to sample a new liqueur called After Shock. Seβn Hynes, with work acquaintances Regine Pedersen, from Vejle in Denmark, and Heather Kennedy, from Roscrea in Co Kilkenny, are also here to chill and maybe dance - without any buckets or mops, and it won't be the same.
Clara Hayes from Lambourne in Berkshire, which is famous for its racehorses (in case you didn't know), and her boyfriend from London, Ben Jones, are ready to rock, too. It's all a bit rocky, really - but we remain "deep cool" throughout, just like the liqueur.
