Christmas Chord Request: All I Want For Christmas is You (Anthem Lights version)

Can anyone post/send the chords to this song? They've done more than just re-record the Mariah Carey version in a higher key. It sounds to me like they've changed many of the chord progressions as well.
I can send you the mp3 if you need it.
...Or you can hear it here:
