St Patrick's Junior Choir in Co Down has missed out on securing their place in the final of Britain's Got Talent.
The school performed to millions of ITV viewers on the live semi-final show last night.
After overcoming a technical glitch, the youngsters opened the show with a rendition of Katy Perry's Roar.
Moments after the music began, hosts Ant and Dec ran back onstage to announce there were a "couple of technical issues" and that the act would be starting the performance again.
Viewers also saw a clip of the pupils at their school in Drumgreenagh, outside Rathfriland.
During the short clip choir members spoke of their experience of taking part in the UK-wide talent show.
One pupil said: "What I love about the choir is that we are all friends."
Another excited pupil said: "On our audition day I saw Ant and Dec but I tried to calm myself down so then I wouldn't get hyper on the stage.
"In our audition everyone was cheering. It was a dream come true."
The choir wowed the BGT judges during their first audition when they performed Keane's Somewhere Only We Know.
The eight to 12-year-olds received a standing ovation from the audience and four thumbs up from Simon Cowell, David Walliams, Amanda Holden and Alesha Dixon.
The kids were asked to audition for the show after winning Radio Ulster's school choir of the year last year.
St Patrick's has only 80 pupils, almost half of whom are in the choir.
Singing director is P4/5 teacher Patricia McCaughey.
"I love teaching the children. They have a lot of fun together and it brings out the best in every child," she said.
Eight acts performed on last night's show.
The youngsters received a positive response from the judging panel.
Walliams said: "I thought it was fantastic and you recovered well from that little technical hitch because I know those things can throw people, but it didn't throw any of you at all.
"A choir like this only works if every single one of you is giving 100% and singing with passion, and you all were.
"It was fantastic to hear you sing a song as a choir that you would actually want to sing." Fellow judge Dixon added: "You guys were first out and that is never easy, and I cannot imagine how nervous you must have been feeling.
"I looked at every single one of your faces and you all looked like you were having the time of your lives.
"Great song choice, you should be so proud."
Holding said of the performance: "I think you did a great job, you represented your school beautifully, and of course Ireland, and I loved the song choice.
"It felt joyful and hopeful, and in light of all the trauma we have been through in the last week, you were a breath of fresh air."
Cowell added: "First half you were kind of getting your groove, second half is when you got your confidence and choreography, and sounded amazing.
"I love your personalities individually.
"That's what makes this choir so special."
Schoolboy singer Kyle Tomlinson and mind-reading pair DNA were announced as the first acts to make it to the finals.
