4th Impact Sing 'Sound of the Underground' in the 2nd Live Show of 'The X Factor UK'

Judges Thoughts:

Simon Cowell said “I thought you looked better than last week, choreography was better, vocal’s great, harmony’s great. You are a band who rehearse like crazy and are ready for the real world. You got a lot of competition in this competition but I thought you did great, I thought you’ve always done great to be honest with you.”

Nick Grimshaw said “I thought that really really worked. When you’re talking about it in the VT, I was like Cheryl’s crazy to put those two songs together but it really worked, I thought it was really really cool. It looked real tonight, I loved it.”

Rita Ora said “What I loved the most is that your identity now has morphed into your own, even though you’re sisters I can see that you’re each individuals at the same time. Vocally it sounded great.”

Cheryl Fernandez-Versini said “You know what this was a collaborative effort, I absolutely loved it, it was fantastic. It was fab!”
