Britain's Got Talent's fourth semi-final is under way with nine more acts hoping to reach Saturday's grand final.
Hosts Ant and Dec introduced opening group Bollywest Fusion who performed a high-tempo routine blending Bollywood moves and contemporary dancing.
All four judges agreed that the act was impressive, and they were also applauded on Twitter.
The Collaborative Orchestra and Singers kicked off their performance of Hey Jude with a pre-recorded segment which featured various members of the group in different parts of the UK.
By the time the cameras hit the auditorium, all 66 members of the group were playing The Beatles classic. It was greeted with a standing ovation.
Alesha Dixon said: "That was epic. This act has got the Royal Variety Show written all over it," while Amanda Holden agreed: "I felt like I was in the Last Night Of The Proms."
Meanwhile, viewers on Twitter commented that the act seemed a little "messy".
Dance group Bespoke Candi wore costumes inspired by The Flintstones, but even their dancing dinosaur could not save them from being buzzed by every judge save Simon Cowell.
"The dinosaur is cute but the act is terrible," said Alesha. She came under fire on Twitter for pressing her fellow judges' buzzers during the dinosaur act.
Simon disagreed: "There's a lot of people who'd pay a lot of money to see this sort of thing."
Since their first audition, Vox Fortura have changed their name (they were formerly Vox Fortis) and lost a band member. However, the one thing that has not changed is their operatic pop rendition of classic songs.
This time, the quartet comprised of two black Americans and two black English vocalists tackled Heroes by the late David Bowie and won a rapturous reception. Alesha once again caused a stir when she called the group "chocolate men".
She said: "Four, sexy chocolate men, polished to perfection. That was sensational."
Dancer Balance Unity, real name Taylor Goodridge, performed a routine which combined streetdance moves with a little comedy.
"I'm not sure you needed everyone else on the stage because you're such a star on your own," said David Walliams.
Host Ant introduced 23-year-old Danny Beard as "the campest" act in this year's series.
The Liverpudlian's distinctive look includes grey and silver make-up and a glittery beard.
But the contestant's rendition of Holding Out For A Hero by Bonnie Tyler did not bowl over all the judges.
Simon hit his buzzer and during the critique that followed, he told the singer: "I thought it was pointless, I've got to be honest with you."
David disagreed: "I thought it was fabulous." The good people of Twitter also had Danny's back, with many nominating him as a potential Eurovision Song Contest contestant.
Part comedian and magician, Christian Lee entertained the crowd when he called upon David to help with his particular blend of magic.
"I'm really glad that this show has given you a platform," David said. Many viewers tweeting along also seemed to agree.
Tumar KR, a robotic dance group from Kyrgyzstan, are Omurzakov, 25, Amazamt, 25, Salamt, 25, and Baiaman, 19.
As the audience shrieked, one dancer twisted his frame into positions that made the judges put their hands over their mouths and eyes.
Their moves were so inventive that Amanda confessed, again, that she still is not sure if they are human. Simon, David and Alesha were also full of compliments for the visually impressive routine. The act seem to have won other celebrity fans watching from home.
Singer Beau Dermott, Amanda's Golden Buzzer act, is only 12. But the youngster from Widnes stunned in the auditions with her rendition of Defying Gravity from the hit musical Wicked.
For the semi-finals, she sang Someone Like You from the musical Jekyll & Hyde and won a standing ovation.
"I'm so proud of you," Amanda told the schoolgirl.
Simon said people such as Beau was the reason Britain's Got Talent exists. He added that in years from now, they would all look back at this moment as the one they discovered a star.
