Sir Bob Geldof gave an emotional speech on tonight's X Factor as he appealed for people to buy the BandAid30 song to help the fight against Ebola.

The former Boomtown Rat, who lives in Davington, near Faversham, made the heartwrenching plea on the hit reality show in advance of the charity track's release tomorrow morning.

Artists who appear on the recording include One Direction, Emeli Sande, Ellie Goulding, Sam Smith, Chris Martin and Bono.

Just before it received its first play on the show, Sir Bob said: "This is hardcore to allow X Factornation to watch this.

“This is the most anti-human disease. We can stop it. We will stop it. We will support those immensely brave NHS workers, those young soldiers who volunteer.

“At 8am tomorrow morning, all of you - this is about us, it could be here. Buy this thing. Don’t get it free. Buy five, buy 10. It’s a great track. Wait till you see this.”

“This is why we did this track. 8am tomorrow X Factor nation we go to war. Buy this song.

Following the track being aired, Kent's X Factor hopefuls survived another week after impressing viewers with their take on Big Band week.

On last night's show, Wilmington's Charlie George from boyband Stereo Kicks, was praised by Simon Cowell for his 'great vocals' after performing Bobby Darin's Mack The Knife.

The eight-piece group had just 24 hours to learn the song after they changed it at the last minute on Friday.

Following the performance there were a few laughs from the audience when Simon Cowell asked their mentor Louis Walsh to name the members.

As he was reeling them off, Simon made his way over to Louis and picked up a notepad in front of him to reveal he had them all written down.

Charlie George, from Chartham, near Canterbury, and Parisa Tarjomani, from Ramsgate, who are part of Only the Young, were also praised for their take on Wanna Be Like You from The Jungle Book.

Louis said: "You're fun and high energy."

Cheryl Fernandez-Versini added: "You add the fun into X Factor."

Tonight's show saw a sing off between Jay James and Stevi Ritchie.

After going to deadlock Jay was sent home after he received the fewest votes from the public.
