The Welsh choir group, which has over 100 male singers, made it all the way through to the final earlier this year.
They finished third overall, behind Jonathan and Charlotte and eventual winners Ashleigh and Pudsey.
Simon Cowell has since been preparing to release a record with the group, and will give them huge publicity ahead of Christmas on next month's X Factor final.
This year will see The X Factor final move to Manchester, the first time in the show's history it will be held outside of London.
Other acts lined up for the big final have been rumoured to include Adele and Beyonce, however they were originally set to duet with the now axed Ella Henderson.
Last year's final saw performances from JLS, One Direction, Leona Lewis, Michael Bublé and Westlife, as well as Coldplay.
The X Factor 2012 continues this Saturday on ITV1 and ITV1HD, with the final five acts sing two tracks each with Abba and Motown themes.
Sunday's results show will see one more act get the axe, and there will be performances from Rhianna and Bruno Mars.
