The Wanted take over Ellen for their first American tv appearance - watch now!

Buy my single and I'll move the sign.

So apparently 2012 is not only the year in which the world ends, but is also the year in which England once again launches a pop invasion of the US.  With Cher Lloyd already gunning for the American charts with 'Want U Back,' fellow teen popstars The Wanted have just upped the ante by performing their UK #1 single 'Glad You Came' on Ellen.

The group have already been trapsing around to radio stations and playing club gigs in seedy eurotrash gay bars, but with a radio re-release of the track slated for January 24, it appears the boys are going big or going home to jolly old England.

The performance itself is pretty by the numbers, with some awkward standing around and then some QUITE THRILLING (read: not thrilling at all) running around in the audience.  But it is notable for being pretty damn on-point vocally, and even for the world's top pop acts that's a big feat these days.  If anyone had doubts these kids have some serious vocal chops this video will go a ways toward silencing them.  But that doesn't mean their infectious brand of UK cheese will make any impact in the charts.

As we've seen lately with everyone from Kylie to Leona Lewis, US success has less to do with quality than it does with quantity and relentlessness of promotion.  Despite a balls-to-the-wall fierce America's Got Talent performance, K-Mo's singles off her latest album floundered outside the dance charts, and with no in-person promotion to speak of, Leona's 'Collide' barely made an impact.  A lot of this is just because the US is so damn big that a few tv and radio spots can't possibly cover the number of people required to have an actual hit, but it's also because the charts have become so homogenized of late that unless you're Katy Perry, Britney or LMFAO, no one is going to play your song anyway.

Sure, the UK gave us Adele, but let's not forget that she also was on most every awards show there was in 2011.  Her whole album was lightning in a bottle, but more importantly, she had the touring and promo schedule to back it up.  The question for The Wanted is whether they are willing and able to do the same, and are ready to sacrifice the time and effort it takes to make it Stateside. 

We're guessing they are - if only just so they can have ultimate bragging rights over JLS.

'Glad You Came' is out to download now in the US, and will be rereleased to mainstream radio on January 24.
