The pair knock the Bingo Players down two places to Number 3, while Disclosure and Aluna from AlunaGeorge climb 26 places to Number 2.
The highest new entry comes from Fall Out Boy at Number 5 with 'My Songs Know What You Did In The Dark', while Little Mix's 'Change Your Life' climbs 19 places to a new peak of Number 12, just shy of their fourth Top Ten in a row.
On the album chart the Les Mis soundtrack climbs back to the Number One 'slot' and real music caricature Jake Bugg climbs four places to Number 2.
This week also marks the one-year anniversary of the release of Emeli Sandé's 'Our Version Of Events', which has spent that entire lifespan inside the Top Ten (!). The album is a non-mover at Number 4 this week.
But where on earth is Kimberley Walsh's 'Centre Stage' album we hear you roar? It's a new entry at Number 18.
