Britain's Got Talent entrants 100 Voices Of Gospel wowed Alesha Dixon to become the second Golden Buzzer act of the new series.
The international choir, featuring singers from the UK and all around the world, entertained with their uplifting rendition of gospel classic This Little Light Of Mine
Judges Dixon and Amanda Holden swayed along and clapped in their seats, while hosts Ant and Dec danced in the wings.
100 Voices Of Gospel received a standing ovation from the audience and four yeses from the panel, including a visibly impressed Simon Cowell and David Walliams.
Before their audition, the group's American lead singer spoke about the prospect of appearing on the Royal Variety Performance, the grand prize for the winning act.
"Our choir consists of 20 nationalities. We have lawyers, policemen, nurses - it's a family affair," she said.
"If we got the opportunity to perform before the royal family, that's the opportunity of a lifetime."
After Dixon hit the Golden Buzzer, which gives the choir an automatic place in the live shows, an annoyed Cowell rued not being quick enough.
"I wanted them," he told her.
"If you snooze, you lose," Dixon replied.
During her critique, the pop star hailed her Golden Buzzer act: "Everything about you, everything you represent, is my idea of heaven."
Jack Higgins, from Liverpool, evoked the plot of Billy Elliot with his appearance in Saturday's episode of the ITV series.
Like the character Jamie Bell plays in the award-winning movie, the 14-year-old has a love of ballet, but it has made him the target of bullies.
"When I started ballet, people were calling me names ... I was getting really upset, but dancing, it just makes me feel happy," he said before his audition.
There were tears as Jack, who performed a ballet routine to Say Something by A Great Big World, talked about the abuse he has endured.
"You know the one thing bullies don't like? They don't like it when you do well," Cowell said as Jack was awarded four yeses.
The show may be called Britain's Got Talent (BGT), but that has not stopped the flow of performers from outside the UK.
Another Kind Of Blue are dancers Antonino from Italy and Violet from the Netherlands.
Their act, a mix of dance and projections, also featured two behind the scenes assistants and the performance creator.
Reminiscent of Hungarian crowd-pleasers Attraction, who won BGT in 2013, Another Kind Of Blue collected four yeses.
Mexican juggler Roberto Carlos and Polish dance group Fair Play Crew are also through to the next round.
Acrobatic act Katy & Paul have been a team for several years. Unlike Paul, Katy is a health care worker and does not perform full-time.
"If Katy's ever at work and unavailable, Paul - I'm here," Walliams quipped as the Liverpudlians took home four yeses.
Jeans, trainers and hoodie-attired Wayne Woodward, a 20-year-old builder from Sutton, proved one cannot judge a book by its cover.
His speaking voice reminded Dixon of EastEnders actor Danny Dyer.
"You sound exactly the same," she said.
"Nah. He sounds like me," Woodward joked.
He went on to surprise everyone with his Frank Sinatra sound-alike rendition of jazz standard, The Way You Look Tonight.
Woodward's excited father stood to cheer his son's audition.
But when he sat back down, to Holden's amusement, he apparently broke his chair.
"I was not expecting this voice to come out," Walliams said as Woodward earned four yeses.
Other acts gaining the panel's approval included soldier Richard Jones, who performed a magic trick, and 60-year-old Bill Brookman, a one-man band on stilts.
