Nile Rodgers and Chic perform in 'special edition' of X Factor
Nile Rodgers and The CHIC Organisation kicked off a "special edition" of Saturday night's X Factor.
Nile has worked with Madonna, David Bowie, Diana Ross and most recently Daft Punk - making them perfect act to perform a three-song medley for this week's Disco theme.
The veteran guitarist, who's career spans five decades, revealed it's the band's last night in the UK before continuing their tour in the US and Japan.
This week didn't include the show's Flash Vote, introduced this season, meaning both of the bottom two acts will be revealed during Sunday's show.
The Mirror reported the show's makers have doubts about the new feature, quoting a source as saying “the Flash Vote isn’t quite working as expected".
Luke Friend kicked off the contestant performances with Play That Funky Music by Wild Cherry.
His performance earned him the labels of "the one to watch" and "the dark horse" from multiple judges.
Kingsland Road jumped in next with Michael Jackson's Blame It On The Boogie.
The group were criticised for letting their serious side get in the way of the performance, but mentor Gary Barlow praised the fact that "they take everything on board".
Tamera Foster chose Wishing On A Star by Rose Royce for this week's performance.
The 16 year-old didn't disappoint, with praise from the panel even higher than previous weeks.
Relight My Fire by Dan Hartman was Sam Callahan's choice for this week.
The singer has praise from Osbourne and Walsh but the other judges were not so kind, with Gary Barlow restating his criticism from last week.
Rough Copy were next up with Earth Wind and Fire's hit September.
The judges couldn't praise them enough, with mentor Barlow calling it "the performance of the night by far".
Abi Alton changed the pace of the evening with an acoustic I Will Survive by Gloria Gaynor.
The "brave" choice of song impressed the panel enough to change even Barlow's mind from last week.
Another MJ hit was up next with Nicholas McDonald performing Rock With You.
It was another hit with the judges too - the only constructive criticism was from Scherzinger:
Hannah Barrett chose Somebody Else's Guy by Jocelyn Brown for this week's show.
It went down well with the panel. Scherzinger said "you showed us how to do disco week right there."
Sam Bailey rounded off the show with Barbra Streisand and Donna Summer's duet No More Tears (Enough Is Enough).
The panel was competing to praise her the most, prompting Sam to admit "I wanna do it again!".
One act will be eliminated in Sunday's show.
Watch the X Factor Results tomorrow night at 8pm on ITV.
