Before they found their way to stardom on Simon Cowell's ITV talent show, the three Watford boys were uploading their own versions of famous tracks on their YouTube channel
X Factor winners Rak-Su have become known for their catchy tracks - but to start with, the group were just a humble trio beat-boxing their way through song covers.
In a clip unearthed from the band's YouTube channel from 2015, Ashley, Mustafa and Jamaal were performing as a trio back in 2015 - with no sign of their fourth member Myles.
Coming from humble roots, the gang were filmed by their mate on an iPhone on the streets of Watford before it was quickly edited and uploaded online.
Performing a beatbox version of My Love by Majid Jordan feat Drake, Jamaal and Mustafa took centre stage before Ashley joined in.
They joked in the description: "We fell in love with this track instantly so decided to do a video for it the day after hearing it... Had a laugh recording this one as always...
"Big Jasper was on the camera for this (iPhone) and has now been hired full time!!"
Despite the clip being shot years ago, it's clear the boys haven't let their newfound fame change them too much - seen wearing baggy jumpers and jeans like they have become known to wear on the ITV talent.
They later added Myles to their line-up by 2017 to make the group complete.
Now, they look set to take on the world as the schoolmates were crowned the winner of X Factor 2017 - beating Grace Davies in the final showdown.
They are the first band to take the win since Little Mix in 2011, and only the second band to win the show overall in its fourteen series run.
As part of their win, they will release their own original song, Dimelo, which they performed as a duet on Saturday night with Wyclef Jean and Naughty Boy.
Performing the song for the second time after they were announced the winners, they were joined by their former finalists, who ran on stage to hug the group for making it through to the end.
This is the first time a champion has released their winner’s single as a duet.
All proceeds from the song will be donated to children’s charities, Together for Short Lives and Shooting Star Chase.
Following the finale this weekend, all the X Factor semi-finalists will be heading out on tour from February next year - with a Sun Online voted wildcard joining them.
Rak-Su, Grace Davies, Kevin Davy White, Lloyd Macey, The Cutkelvins and Matt Linnen will be serenading the UK in stadiums - but who do you want to see join them?
SIMON COWELL has revolutionised this year's X Factor tour.
The all-new puts the power back in the audience's hands, as each night our finalists battle it out for fans' votes just like they do on Britain's most exhilarating TV show.
