Niall Horan welcomed some very special guests to the 3Arena as he brought his Dinner Party tour to a close in Dublin, with Irish band Kingfishr joining him on stage.

The former One Direction singer played four massive gigs in the Dublin venue this week, pulling out all the stops for fans who gathered from far and wide.

Of course, many artists save the best for last, and Niall was no exception, bringing out the Irish folk band Kingfishr to join him for the final few songs of his show at the arena on Friday night.

While many expected the lads to join Niall in a cover of one of his own songs, Niall handed the reins over to the band themselves, letting them play The Sun Will Never Settle to thousands of fans.

It wouldn’t be a Kingfishr performance without their mega-hit ‘Killeagh’, and the band didn’t disappoint, with Niall joining them on stage for a rendition of the fan favourite. The performance quickly won over fans, with clips being shared and celebrated by music lovers around the world.

‘Seething with jealousy for everyone who got to experience this,’ one commented, while another added: ‘The collab we never knew we needed.’

‘When you’re the guest appearance and the crowd knows every word to your song… That’s how you know your country loves ya,’ another wrote, while another commented: ‘INSANE!!!! I’d give anything to have been there.’

While there are, of course, the planned appearances such as Kingfishr, Niall was surprised to see an old primary school teacher of his in the crowd during night one — without whom, the lineup of One Direction might have looked very different.

‘Oh my God, I’ve just spotted my third-class teacher, Mrs Anne Caufield,’ Niall told the crowd as she smiled back up at him.

The singer continued: ‘Anne is the reason I started singing … She gave me my first solo part in Away in a Manger, when I was about five or six years old.

‘She then gave me the part of Oliver in the play Oliver Twist. To be fair there was a bit of bias because I was in your class. You could have picked your son to be fair.

‘She really is the reason I started doing all of this, give it for Anne, come on.’ The crowd then erupted in applause for the teacher.
