A musical theatre boy band and an illusionist became the first two acts to make the final of Britain's Got Talent 2014 after they won through against seven others in the first semi-final.
Singing group Collabro won the public vote and, after the show's judges were split 2-2 between Canadian conjurer Darcy Oake and impressionist Jon Clegg, Oake went through on the public vote.
Just 45 acts made it through to the live semi-finals from the thousands who applied and the hundreds who auditioned.
Judge Alesha Dixon said of Collabro: "That was perfection, I love you guys."
Fellow judge Amanda Holden said: "Every single one of you has got the most beautiful tone to your voice. I think we could be looking at the winners of Britain's Got Talent."

George Sampson won Britain's Got Talent in 2008 after winning fans with his impressive dancing in the rain. The youngster, now 19, has since appeared on stage and in Natwest advertising campaigns. He made his cinema debut in Streetdance 3D and went on to star in Waterloo Road and Mount Pleasant.
8/8 2007 - Paul Potts
Paul Potts won over Simon Cowell with his rendition of Nessum Dorma and went on to become Britain's Got Talent's first victor. Potts has enjoyed a successful operatic career since the competition, with Harvey Weinstein even making a biopic of his life starring James Corden in the lead.
And show supremo Simon Cowell said: "Britain really has got talent, congratulations."
Oake disappeared from underneath a blanket on a platform on the stage and reappeared down below, causing Cowell to say: "It's really difficult to guess how you did that, you've got an incredible stage presence, and it's believable."
Clegg delighted the audience with his impressions, which included hosts Ant and Dec.
Cowell said: "It was fantastic, you had the audience in the palm of your hand. It was clever, normally I don't know who half the people are, your Dec was brilliant, seriously good."
Dec complained: "I don't know why you do me so camp."
There was controversy over Christian Spridon, a waiter living in London who had won the support of judge David Walliams earlier in the competition. Walliams chose him as his golden buzzer act.
Spridon performed The Weather Girls' "It's Raining Men", leading Dixon to say: "It was so out of tune it's ridiculous."
Another group of acts will try to impress viewers when the second live semi-final takes place at 7.30pm tonight.
