Forget the sing-offs and dismissals; the most brutal part of The X Factor process comes when the cameras stop rolling. Seriously, survey the pop battlefield and you’ll find it metaphorically strewn with the corpses of also-rans. Shayne Ward? Banished to the West End with Justin Lee Collins. Andy Abraham? Last seen on the identity parade of ‘Nevermind the Buzzcocks’. Rhydian? We heard a (malicious) rumour he’s moonlighting as a Kryten impersonator at ‘Red Dwarf’ conventions… Hurrah for JLS, then, who’ve shown, with Jukebox, that they’re still hitting career highs three albums down the line.
