What Band Does That COOL SONG In The Zales Holiday Commercial?

If, like me, you've been seeing A LOT of the above commercial, then you also appreciate Zales going to the trouble of using a cool song because any other song would be drioving us up the wall by now.  I mean, I'm here right now watching a college football, for freak's sake, and the Zales spot plays during EVERY SINGLE COMMERCIAL BREAK.

So what's the song, and who does it?

The song is called "If It Wasn't For You" and he band that performs it is British band Various Cruelties.  The band is led by singer/songwriter Liam O'Donnell, a self-confessed Strokes fan enamored by the NYC hipster scene.  The band's self-titled album came out in April on the esteemed Rough Trade label and, despite the interest this commercial will no doubt create, a precursory check of their website reveals no shows on their schedule.
