The X Factor, love it or hate it, is back on the telly again. Last week saw this year's auditions come to an end so now those who’ve gone through to the next round (including Irish busker brothers Sean and Conor Price) will face the Bootcamp stage. Judges Simon Cowell, Nicole Scherzinger, Sharon Osbourne and Louis Walsh set the contestants a series of tests to demonstrate their ability to sing and dance. First, the contestants face the 'Wall of Songs', where they must race and fight for a tune to perform in a group of four. If their ensembles are successful, they’ll progress to the next stage of Bootcamp.
