[SOLVED] Last Christmas I Gave You My Heart??

Okay, so, who's the guy that sings that Last Christmas I Gave You My Heart song at Kohl's?? it'd be greatly appreciated if anyone could tell me the answer and/or provide me a link. thanks~

Hi, do you mean this:

Wham! - Last Christmas http://www.youtube.com/watch?v=TC4hztitRcw

Mmm, no. I looked at that song beforehand, and it's not the same beat.
The one I'm referring to is upbeat, and almost pop-ish. Can't exactly put a finger on the tune, but it's the same lyrics, a few high-pitched notes, but the voice sounds almost similar to that of Wham!'s..

I totes found it. It's Darren Hayes, Last Christmas. A customer came into the store, and it was literally my last customer before we closed the store, and she had a song identifier on her phone and caught it for me.

First 15 seconds are irrelevant to the entire song. But, I am happy.
