It was the last day of auditions and one of the acts hoping to impress were Zyrah Rose, a girl group from London.
Made up of Christine (25), Kara (28), Charlotte (28) and Emily (29), Zyrah Rose currently have a variety of day jobs from teachers to waitresses.
The girls got together as a group around 2 years ago and were previously signed to a label before being dropped.
"Obviously there's that disappointment there," the girls said, "But we don't want to break up, we want to stay together and be successful."
"I reckon the Queen would like us, I think she'd appreciate our music," the "classy" group went on to tell cameras.
They sing a unique rendition of Ed Sheeran’s I See Fire for the judges who are blown away by the vocals.
"YES!" exclaimed Alesha Dixon following the powerful performance. "What is there not to like? You're brilliant, I love it!"
Amanda Holden agreed: "It was stunning, it was really wonderful to watch, it was amazing."
But what did ever hard to impress Simon Cowell have to say?
"You were like four kind of statues just singing," he complained, "You were left like I was a bit cold."
Fighting for Zyrah's corner, Alesha said: "I wouldn't have changed a thing, I've got your back girls."
Despite Simon's reservations, he joined the other judges in giving Zyrah a yes through to the next round.

And don't forget it's the start of the live shows tomorrow (Sunday) with the first heat from 7:30PM.
